Абстракт
In this study, calcite was tamed by using traditional methods. Crystal structure of
calcite in phase shifts was analyzed after burning it in +300º C, +500 º C, +800 º C,
+1200 º C, and +1400 º C by using Shimadzu XRD-7000 X-ray diffractometer, HA-
1001, and TTK-450 apparatus. Moreover, elements contained in traditionally tamed
calcite with enrichment were determined.
After taming, calcite turned to bright yellow, flour like soft substance with bitter and
sour taste. Results of phase analysis at various temperatures were as following: At
+300º C, CaCO3 -84.23%, CaC2-15.77%; at +500 º C, CaCO3 -58.86%, CaC2-14.14%;
at +800 º C, CaCO3-23.56%, CaC2 -76.44%, at +1200 º C, CaCO3 -14% CaC2 -86%
and at +1400 º C, CaCO3 -28.11%, CaC2 -71.89%.
By spectrophotometer following elements were determined in tamed calcite with
enrichment: Ca-36.12%, Ti-0.0005%, Ni-0.001%, Cu-0.0003%, Mn-0.03%, and Sr-
0.015%.
