Properties And Utilizes Of Chromium Oxide Green

Chrome Oxide pigment known as Chrome Oxide Green. there have quite a few preparation of chrome oxide approach. but generally has three sorts: by chromium hydroxide preparation process of chrome oxide green, ammonium sulfate sodium chromate salt decomposition technique, chromium anhydride direct decomposition technique.

The thermal decomposition of ammonium sulfate sodium chromate salt, is the Usa, Britain, Germany and other nations along with the simple solutions of production of chrome oxide green, has come to be the largest output in preparing chrome oxide green, ideal high quality, most varieties of production procedures. its benefit is somewhat easy production course of action, cost reduce than that of chromic acid decomposition approach, wide adaptability, began in the rotating mass production. the production approach of standard will not make dangerous gas. chromic acid decomposition system rapidly in recent years . with the consciousness of chrome 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 power is strong, high temperature resistant, weather resistant, insolube in water, inside 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 supplies. 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, very good paint excellent and fastness.

Chrome oxide green might be applied for smelting metal chromium and chromium for creating stainless steel, auto components , tools, tapes and videos. chromium cross the rust on metal simultaneously, robust and gorgeous. applied for enamel, glass business,creating components. especially for the production of Ceramic Pigment, bright colour merchandise.

At home and abroad, because the global economic recovery, creating materials, coating paint, plastic, ink along with other industries in the speedy growth, the demand of inorganic pigment also increase quickly. with all the fast development of coating market, as 1 in the main raw material for inorganic pigment obtained speedy improvement. boost the level of atmosphere security of inorganic pigment, using has got broadly recognized business enterprises, environmental protection inorganic pigment improvement direction on the trend of your times.
