铬铁矿是提取铬铁的唯一重要工业矿物。铬铁用于炼制各种普通合金钢和特殊合金钢。氧化铅(Cr_2O_3)、铬酸酐(CrO_3)是一种有机催化剂,广泛用于化工部门和石油化工部门,由铬铁矿与碱制成的重铬酸盐是化学工业上的重要原料。铬系耐火材料具有熔点高、对任何成分的炉渣都十分稳定,在高温下又不发生收缩等特点,在冶金和焦化部门用途广。铬铁矿是新型工业材料—各种铸石的结晶促进剂。近十几年来研制出来的新型氧化物半导体材料—铬酸镧(LaCrO_3)导电性能良好,在氧化气氛下十分稳定,PbCr_2Se、CoCr_2S_4是一种铁氧体,这些材料用于宇宙探索和海洋开发等重要技术领域。掺
Chromite is the only important industrial mineral extracted from ferrochrome. Ferrochrome is used to refine all kinds of ordinary alloy steel and special alloy steel. Lead oxide (Cr 2 O 3) and chromic anhydride (CrO 3) are organic catalysts that are widely used in the chemical and petrochemical sectors. Dichromates made from chromite and alkali are important raw materials for the chemical industry. Chromium-based refractories have a high melting point and are highly stable to any component of slag and do not shrink at elevated temperatures. They are widely used in metallurgical and coking sectors. Chromite is a new type of industrial materials - a variety of cast stone crystallization promoter. LaCrO_3 (LaCrO_3), a new type of oxide semiconductor material developed in recent ten years, has good conductivity and is stable under an oxidizing atmosphere. PbCr_2Se and CoCr_2S_4 are ferrites, which are used in the exploration of the universe and marine development. Important technical areas. Doped
