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 3 kinds: by chromium hydroxide preparation technique of chrome oxide green, ammonium sulfate sodium chromate salt decomposition method, Chromium Oxide Green direct decomposition method.

The thermal decomposition of ammonium sulfate sodium chromate salt, is the United states of america, Britain, Germany and other nations and also the fundamental methods of production of chrome oxide green, has become the biggest output in preparing chrome oxide green, very best quality, most varieties of production methods. its advantage is relatively easy production procedure, price reduce than that of chromic acid decomposition technique, wide adaptability, started within the rotating mass production. the production procedure of basic doesn't create harmful gas. chromic acid decomposition technique fast in current years . using the consciousness of Chromium Oxide Green. chromic anhydride in 1999 made 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 power is powerful, higher temperature resistant, weather resistant, insolube in water, in the atmosphere is steady. superb weatherability, meet thermal stability, melting point 2265 degrees celsius, the boiling point of 3000 degrees celsius, is of high quality refractory supplies. chrome oxide green chemistry, insoluble in water, acid and organic solvents, slightly soluble in concentrated sodium hydroxide solution, soluble in hot or boiling sodium bromate answer of sulfur phosphorus mixed acid, great paint high quality and fastness.

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

At home and abroad, because the global economic recovery, building supplies, coating paint, plastic, ink as well as other industries within the rapid development, the demand of inorganic pigment also improve rapidly. using the rapid improvement of coating industry, as one from the primary raw material for inorganic pigment obtained rapid improvement. enhance the level of environment security of inorganic pigment, using has got extensively recognized industry enterprises, environmental protection inorganic pigment improvement path of the trend of the times.
