Properties And Uses Of Chromium Oxide Green



Chromium Oxide Green pigment known as chrome oxide green. there have numerous preparation of chrome oxide procedure. but basically has three sorts: by chromium hydroxide preparation technique of chrome oxide green, ammonium sulfate sodium chromate salt decomposition method, Chromium Oxide Green direct decomposition technique.

The thermal decomposition of ammonium sulfate sodium chromate salt, is the United states, Britain, Germany and other nations and the basic methods of production of chrome oxide green, has turn out to be the biggest output in preparing chrome oxide green, best quality, most varieties of production methods. its benefit is relatively simple production process, cost reduce than that of chromic acid decomposition technique, wide adaptability, started in the rotating mass production. the production process of basic doesn't create harmful gas. chromic acid decomposition technique quick in recent years . with the consciousness of Chromium Oxide Green. chromic anhydride in 1999 produced chrome oxide production twice about chromium.

The physical properties of chrome oxide green. chrome oxide green with metallic luster. colour is light green to dark green. magnetism,covering energy is powerful, higher temperature resistant, climate resistant, insolube in water, in the atmosphere is stable. excellent weatherability, meet thermal stability, melting point 2265 degrees celsius, the boiling point of 3000 degrees celsius, is of high quality refractory materials. chrome oxide green chemistry, insoluble in water, acid and organic solvents, slightly soluble in concentrated sodium hydroxide answer, soluble in hot or boiling sodium bromate solution of sulfur phosphorus mixed acid, great paint quality and fastness.

Chromium Oxide Green may be used for smelting metal chromium and chromium for creating stainless steel, auto parts , tools, tapes and videos. chromium cross the rust on metal simultaneously, strong and beautiful. used for enamel, glass industry,developing materials. especially for the production of ceramic pigment, bright color products.

At home and abroad, as the global financial recovery, developing materials, coating paint, plastic, ink and other industries in the fast growth, the demand of inorganic pigment also improve quickly. with the fast development of coating industry, as one from the main raw material for inorganic pigment obtained rapid improvement. improve the level of environment security of inorganic pigment, using has got extensively recognized business enterprises, environmental protection inorganic pigment improvement path from the trend from the occasions.
