“X-Ray Diffraction” continued in a raw material sample. In this example, we simply matched the peaks that we measured for the sample with a pattern from the minerals database to identify the material. This is usually done with an automated search/match software tool. The search/match and identification is very simple for this example, but for some samples the identification can be much more difficult. In many cases, also having a chemical analysis significantly improves the confidence in a match. While the example shown in Figure 4 for quartz is relatively simple, the pattern for most raw materials is considerably more complicated and contains various amounts of several minerals. The X-ray diffraction pattern for a shale is shown in Figure 5. The chemical analysis for this sample, as measured by X-Ray Fluorescence, is shown in Table 2. In this example, we have taken the analysis to the next level and estimated how much of each mineral (phase) is present. The first step in this analysis is identification of the minerals using the search/match tool. In this case, the sample appears to contain quartz, kaolin, some mica type material (muscovite), rutile, and some material we could not identify. A known amount of zinc oxide (ZnO or zincite) has been added to the sample to help with the next step. Once we have a good idea about what phases are present, we can estimate how much of each is present using something known as a whole pattern fitting technique. In this analysis we use the relative intensity of each phases, which we get from the ICDD database. The relative intensity is shown in Figure 4 as the RIR on the right side of the report. For example, the RIR for quartz is approximately 4 while kaolin is 1. This means that for equal amounts of quartz and kaolin, the peaks for quartz would be approximately 4 times larger than the kaolin peaks. Using this parameter and information on each phase from the database, the software attempts to recreate the measured diffraction pattern by varying the amount of each phase until the difference between the measured pattern and the fitted pattern are as small as possible. The known addition of ZnO that was mentioned earlier can then be used to further refine the fit. The ZnO is not part of the final estimation of phase content or chemical analysis since it is just added to act as an internal standard and January 2019 · BRICKYARD · 19
“X-Ray Diffraction” continued improve the analysis. In the end, the software also identification is good (and this can be hard for some reports a calculated chemistry based on the selected of the phases that are present in very small amounts), phases and amount of each phase calculated by the and we have a chemical analysis to compare to, we whole pattern fitting. This calculated chemistry can be fairly confident in the results. Whole pattern should be checked against the measured chemistry fitting should be used mostly as a comparative tool to determine how good the fit is. The calculated and and less as an absolute tool. Having said this about whole pattern fitting, X-Ray Diffraction is the primary tool to measure and quantify the crystalline phases of quartz in a sample. It is used for everything from raw materials to filter samples taken from OSHA exposure tests. For more information about this please see “Understanding Silica” (Brickyard, July 2008, pg. 12). For this type of analysis, known as an external standards method, a series of standards have been created specifically for this analysis to improve the quality of the analysis. One last thing to point out about X-ray diffraction is that we can also use it on fired products to determine how much glassy material may be present. This is another indication of how well fired something is. Glass is by definition amorphous or lacking a regular structure. Instead of sharp peaks like you see in Figure Figure 5: Typical X-Ray Diffraction Pattern for a Raw Material measured chemistries will likely never match exactly since there will be some trace material that we cannot HALBERT MILL COMPANY identify, and we do not know the composition of the amorphous or glassy phase, but it should be similar with the same general elements. P.O. Box 927 A word of caution is needed at this point about whole pattern fitting. This type of determination is not a Jacksonville, TX 75766 quantitative result like the chemical analysis where we have multiple traceable standards for each element. Unfortunately, we do not have phase standards www.halbertmill.com for X-Ray Diffraction, so the results can only be considered semi-quantitative at best.

For this example, the SiO2 content was actually fairly high for a brick based on the chemical analysis shown in Table 3 but the actual quartz content is roughly half that based on the whole pattern fitting analysis shown in Figure 6. The remaining SiO2 shown in the chemical analysis is distributed in the glass and other phases. X-Ray diffraction is a tool that is used to determine the structure of materials including the amorphous content of fired brick. It is also used to determine the crystalline silica content of materials. In conjunction with chemical analysis, X-Ray Diffraction gives a very complete picture of the composition of a material. If you have specific question about material analysis using X-Ray Diffraction, do not hesitate to contact us at the NBRC. ■ Figure 6: Typical X-Ray Diffraction Pattern for Fired Sample 22 · BRICKYARD · January 2019

So, I felt pretty good about where I was at 75 and how “up-to-date” I was. Then, one night last week, the bottom fell out. My wife was staying up late to finish a presentation she was working on so I decided to stay up and watch TV until she got finished. It was about 11:30 PM so I tuned in the various late night shows on the 3 main networks (Jimmy Fallon on NBC, Jimmy Kimmel on ABC, and Steven Colbert on CBS). I went back and forth between the 3 shows for about 30 minutes just to see who the guests were. It soon dawned on me that I had NO idea who any of these people were. Some were from the movies, some from TV, and some were performers (mostly singers) and I had never heard of any of them (and, based on the way some of them sounded, that was probably a good thing). I felt so out of place that I changed over to the Food Network and watched some reruns of “Diners, Drive-In’s, and Dives”. Now, that’s real entertainment. At least I know good food when I see it! By the way, the next morning, my 15-year old grandson came over and I asked him about the people I had seen on TV. He explained to me who each one was and how popular they were. He couldn’t believe that I didn’t know them. I asked him who Steve Allen, Jack January 2019 · BRICKYARD · 25

Brick and Heavy Clay Manufacturers Short Course DATE: March 18-21, 2018 The Brick Short Course is an outgrowth of the original Plant Operator’s Forum that was held in 1956. The course is a combination of lectures on all aspects of brick manufacturing reinforced by hands-on-testing of raw materials and brick from each student’s plant. The course follows material through the plant, and lectures are included on factors that are used to judge the quality of brick products. This course is for anyone interested in the technology of manufacturing – from Plant Supervisors to Presidents and is recommended for those employees that want to gain new skills to further help them advance in their usefulness to their employers. REGISTRATION FORM is available at: https://brickandtile.org/short-course-registration/ REGISTRATION FEE: $425.00 for NBRC Members $1,200.00 for Non-Members https://brickandtile.org/short-course-registration/ LOCATION: The National Brick Research Center/Bishop Materials Laboratory 100 Clemson Research Boulevard Anderson, SC 29625 Tel: 864-656-1094 Email: brick@clemson.edu Web site: www.brickandtile.org January 2019 · BRICKYARD · 27
