Kazazian Cyprus Industrial Minerals Company Talc Division 555 South Flower Street Dos Angeles, California 90071 Dear MSD Kazazian: In response to your letter of 30 July 1981, I have enclosed the diffraction pattern of the monoblend talc sample #110865. The diffraction pattern is of a chrysotile single fiber taken at 200 kV. The sample contained a very small amount of chrysotile and may have been a contaminant. The very small size of the single fibers (--340 A diameter) make it difficult or impos sible to get a diffraction pattern using less than 200 kV, You had mentioned that you were using low kV, I feel that this could be the problem with seeing the pattern. Please contact me if you have any questions. Sincerely, Richard M. Ellis, Jr, Research Microscapist RMElfe Enel. Ref: 5500 ^ uEXTHtIBfITfs CAM-126 2S20 SOUTH MICHIGAN AVENUE * CHICAGO.
