Properties And Uses Of Chromium Oxide Green



Chromium Oxide Green pigment called chrome oxide green. there have numerous preparation of chrome oxide process. but essentially has three 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, Britain, Germany and other countries and the fundamental techniques 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 methods. its advantage is relatively simple production procedure, price reduce than that of chromic acid decomposition technique, wide adaptability, started within the rotating mass production. the production procedure of basic does not create harmful gas. chromic acid decomposition technique quick 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. color is light green to dark green. magnetism,covering energy is strong, high temperature resistant, weather resistant, insolube in water, within the atmosphere is steady. excellent 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 solution, soluble in hot or boiling sodium bromate answer of sulfur phosphorus mixed acid, good paint quality and fastness.

Chromium Oxide Green can be utilized for smelting metal chromium and chromium for creating stainless steel, auto components , tools, tapes and videos. chromium cross the rust on metal at the same time, strong and beautiful. utilized for enamel, glass business,building materials. especially for the production of ceramic pigment, vibrant color goods.

At home and abroad, as the international financial recovery, developing materials, coating paint, plastic, ink as well as other industries within the fast development, the demand of inorganic pigment also increase rapidly. with the rapid improvement of coating industry, as one of the main raw material for inorganic pigment obtained fast improvement. improve the degree of environment safety of inorganic pigment, utilizing has got extensively recognized industry enterprises, environmental protection inorganic pigment improvement direction from the trend from the times.
