Properties And Uses Of Chromium Oxide Green



Chromium Oxide Green pigment called chrome oxide green. there have many preparation of chrome oxide process. but essentially has 3 kinds: by chromium hydroxide preparation method 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, will be the United states of america, Britain, Germany as well as other nations and the fundamental methods of production of chrome oxide green, has turn out to be the biggest output in preparing chrome oxide green, best high quality, most varieties of production techniques. its benefit is fairly simple production procedure, cost reduce than that of chromic acid decomposition method, wide adaptability, began in the rotating mass production. the production procedure of fundamental does not 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. color is light green to dark green. magnetism,covering power is strong, high temperature resistant, climate resistant, insolube in water, in the atmosphere is stable. superb weatherability, meet thermal stability, melting point 2265 degrees celsius, the boiling point of 3000 degrees celsius, is of top 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, good 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 beautiful. used for enamel, glass business,developing materials. particularly for the production of ceramic pigment, vibrant colour products.

At house and abroad, as the international economic recovery, building supplies, coating paint, plastic, ink and other industries in the fast growth, the demand of inorganic pigment also increase rapidly. with the rapid development of coating industry, as one of the main raw material for inorganic pigment obtained rapid development. enhance the degree of atmosphere security of inorganic pigment, using has got extensively recognized business enterprises, environmental protection inorganic pigment improvement path of the trend of the occasions.
