Properties And Utilizes Of Chromium Oxide Green

Chromium Oxide Green pigment known as chrome oxide green. there have numerous preparation of chrome oxide procedure. but essentially has 3 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 countries and the basic methods of production of chrome oxide green, has become the biggest output in preparing chrome oxide green, best quality, most varieties of production techniques. its advantage is fairly easy production process, cost lower than that of chromic acid decomposition technique, wide adaptability, started in the rotating mass production. the production process of fundamental doesn't produce dangerous gas. chromic acid decomposition technique quick in current years . using 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 strong, high temperature resistant, weather resistant, insolube in water, within the atmosphere is stable. superb 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 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 at the same time, strong and stunning. utilized for enamel, glass business,building materials. particularly for the production of ceramic pigment, bright color goods.

At home and abroad, because the global financial recovery, developing supplies, coating paint, plastic, ink and other industries within the fast growth, the demand of inorganic pigment also increase quickly. using the fast improvement of coating industry, as one from the primary raw material for inorganic pigment obtained fast improvement. enhance the level of environment security of inorganic pigment, utilizing has got widely recognized business enterprises, environmental protection inorganic pigment improvement direction from the trend from the occasions.
