Properties And Uses Of Chromium Oxide Green



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

The thermal decomposition of ammonium sulfate sodium chromate salt, is the United states of america, Britain, Germany as well as other nations and also the basic methods of production of chrome oxide green, has turn out to be the largest output in preparing chrome oxide green, best quality, most varieties of production techniques. its advantage is relatively easy production procedure, cost reduce than that of chromic acid decomposition method, wide adaptability, started in the rotating mass production. the production procedure of fundamental doesn't produce harmful gas. chromic acid decomposition technique quick in current 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, weather 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 solution, soluble in hot or boiling sodium bromate solution of sulfur phosphorus mixed acid, good paint quality and fastness.

Chromium Oxide Green can be utilized for smelting metal chromium and chromium for making stainless steel, auto components , tools, tapes and videos. chromium cross the rust on metal at the same time, strong and stunning. utilized for enamel, glass industry,developing supplies. particularly for the production of ceramic pigment, bright colour products.

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