Ceramic glaze Iron chromite powder陶瓷釉料铬精粉是一种天然的无机矿物粉末。它是一种以FeO和Cr2O3为主要成分的复合矿物。铬矿粉的质量来自于不同品位的铬矿砂的品质。我厂选用46-50%含量和40-42%的非洲铬矿为原料，采用先进的研磨设备和备制方法，得到适合色料和铸造冶金领域的铬铁矿粉。
Iron Chromite flour is a natural inorganic mineral powder. It is a composite mineral mainly composed of FeO and Cr2O3. The quality of chromite flour comes from the quality of chromite sand of different grades. Our factory uses African chromite with a content of 46-50% and 40-42% as raw materials, and adopts advanced grinding equipment and preparation methods to obtain chromite flour suitable for pigments and casting metallurgy fields.
