High purity chromium has good toughness. Non-iron based precision alloy with high temperature and corrosion resistance, especially the necessary material of chromium base alloy, has important applications in the fields of aerospace industry, jet aircraft manufacturing and gas turbine manufacturing.
In order to avoid iron, silicon, aluminum and other impurities, industrial production of high purity chromium must rely on electrolysis.
Chromium trioxide is an important chromium compound and a strong oxidizer. Mainly used in the electroplating industry, making the raw materials of electroplating chromium such as bicycle, watch, instrument and daily use hardware, and also used in manufacturing high purity metallic chromium. It is the raw material of low temperature conversion catalyst, high temperature conversion catalyst and high pressure methanol synthesis catalyst.
In the process of producing high purity chromium, chromic trioxide is prepared into electrolyte and electrolyzed through electrolysis cell, and finally metal chromium is deposited.
