青云耐火材料氧化铬绿

【 chrome oxide green product introduction 】 :

chrome oxide green (also known as chromium trioxide, chrome oxide), chrome oxide green by chromic acid, sodium or potassium dichromate and sulfur etc. after the high temperature roasting. or by the thermal decomposition of ammonium dichromate. high temperature resistant, light resistance, resistance to all kinds of chemicals. the pure products of infrared reflection close to natural chlorophyll mohs hardness close to alumina (al2o3), second only to diamond. with metallic luster, magnetism, covering power is strong, high temperature resistant, weather resistant, insoluble in water, soluble in acid, to be stable in the atmosphere for the average concentration of acid and alkali and sulfur dioxide gas no effect, good paint and fastness. insoluble in water, acid and organic solvents, slightly soluble in concentrated sodium hydroxide solution, soluble in hot, hot perchloric acid solution of sodium bromate solution or boiling sulfur phosphorus mixed acid. light, atmosphere, and corrosive gases (h2s, so2, etc.) is extremely stable, excellent weather resistance. stability when it is heated, it is of high refractory materials. chromium trioxide is mainly used in metallurgy, pigment, grinding and polishing, fire-proof material and developed new melt spray paint, etc.

【the purpose of the chrome oxide green】 :

chrome oxide green used for smelting metal chromium and chromium carbide, enamel, ceramic, glass, leather, refractory materials, building materials, color, organic synthesis catalyst, making fast material and special ink printing paper, metal polishing materials, metal surface chromizing, magnetic materials, etc. used in paints, ceramics, rubber, art paint, and camouflage coatings, etc.
