ROW MATERIAL MIXTURE FOR OBTAINING OF ARTIFICIAL EMERALDS

摘要

FIELD: chemistry.;SUBSTANCE: row material mixture for obtaining of artificial emeralds includes (weight parts): green packing glass 56-62; litharge 2-3; soda 11-13; borax 7-8; saltpeter 1-3; chromium carbonate 1/3-2/3. The obtained artificial emeralds possess saturated green colour and typical mineral glance. The temperature of components fusion is 970-1000°C.;EFFECT: components fusion temperature decrease of row material mixture.;1 tbl
