Properties And Uses Of Chromium Oxide Green

Chromium Oxide Green pigment called chrome oxide green. there have many preparation of chrome oxide process. but basically has 3 kinds: by chromium hydroxide preparation technique of chrome oxide green, ammonium sulfate sodium chromate salt decomposition technique, Chromium Oxide Green direct decomposition technique.

The thermal decomposition of ammonium sulfate sodium chromate salt, will be the United states, Britain, Germany as well as other nations and the fundamental techniques of production of chrome oxide green, has become the largest output in preparing chrome oxide green, very best quality, most varieties of production methods. its benefit is fairly easy production process, cost reduce than that of chromic acid decomposition method, wide adaptability, started within the rotating mass production. the production process of basic doesn't produce dangerous gas. chromic acid decomposition method quick in recent years . with 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 energy is strong, high temperature resistant, climate resistant, insolube in water, in the atmosphere is steady. 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 answer of sulfur phosphorus mixed acid, great paint quality and fastness.

Chromium Oxide Green can be used for smelting metal chromium and chromium for making stainless steel, auto parts , tools, tapes and videos. chromium cross the rust on metal simultaneously, strong and beautiful. utilized for enamel, glass business,developing supplies. especially for the production of ceramic pigment, vibrant color goods.

At house and abroad, because the international economic recovery, building supplies, coating paint, plastic, ink as well as other industries within the fast growth, the demand of inorganic pigment also increase rapidly. with the rapid development of coating business, as 1 from the primary raw material for inorganic pigment obtained rapid improvement. enhance the degree of atmosphere security of inorganic pigment, utilizing has got widely recognized business enterprises, environmental protection inorganic pigment development path of the trend of the occasions.
