氧化铬绿为六方晶体系列或无定形橄榄绿色粉末，用于冶炼金属铬和碳化铬、陶瓷、研磨、抛光、涂料及油墨等工业。

1、溶于热的碱金属溴酸盐溶液，不溶于水、醇、酸和碱。

2、与许多二价金属的氧化物一起加热至高温能生成尖晶石型化合物。

3、具有α-Al2O3结构，Cr2O3对酸碱都具有较好的稳定性，与酸碱一般不反应。三价铬的氢氧化物，Cr(OH)3具有两性，能够与酸碱发生反应。

4、经过灼烧的Cr2O3，类似于刚玉，不溶于酸，但可用熔融法使它变为可溶性的盐。如Cr2O3与焦硫酸钾在高温下反应：Cr2O3+ 3K2S2O7=3K2SO4+ Cr2(SO4)3。

元丰氧化铬绿用于冶炼金属铬和碳化铬，搪瓷、陶瓷、玻璃、人造革、耐火材料、建筑材料的着色、催化剂、制造耐晒材料和印刷的用油墨、金属抛光研磨材料、金属表面渗铬、磁性材料等；氧化铬绿用于涂料、陶瓷、橡胶、美术颜料等。

颜料级氧化铬绿统煅烧铬酸酐方式生产的一种氧化铬绿产品，产品着稳定性比较强，用于地坪、建筑材料等行业。

陶瓷级氧化铬绿是高温煅烧烧铬酸酐方式生产的一种产品，用于陶瓷色釉等陶瓷行业。

Chrome oxide green

Chrome oxide green for the six-party crystal or amorphous olive green powder series, density: Melting point: 2266 degrees. Boiling point: 4000 degrees. A metallic luster, have magnetic, strong hiding power, high temperature , weather , insoluble in water, soluble in acid, soluble in hot alkali metal salt solution. Chrome oxide green to be stable in the atmosphere for the average concentration of acid and alkali and sulfur dioxide gas no effect, good paint quality and fastness. Light, air, high temperature and corrosive gas is extremely stable, has good covering power. Chrome oxide green is mainly used for smelting metal chromium and chromium carbide, ceramic, grinding, polishing, coating and printing ink industries.

Chrome oxide green features

1, soluble in hot alkali metal salt solution, insoluble in water, alcohol, acid and alkali. Light, air, high temperature and corrosive gases such as sulfur dioxide and hydrogen sulfide are extremely stable, strong hiding power, poisonous.

2, with a lot of divalent metal oxide heated to high temperature and can generate spinel compounds.

3, with alpha Al2O3 structure, Cr2O3 had a good stability in acid and alkali, reaction with acid and alkali is generally not. Trivalent chromium hydroxide, Cr (OH) 3 with both sexes, can react with acid and alkali.

4, after calcination of Cr2O3, dense crystal type, similar to the corundum, insoluble in acid, but available melting method to make it into a soluble salt. If Cr2O3 reaction at high temperatures: potassium sulphate with focal Cr2O3 + 3 k2s2o7 = 3 + k2so4 Cr2 (SO4) 3.

Chrome oxide green

Chrome oxide green used for smelting metal chromium and chromium carbide 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. Chrome oxide green used in coating, ceramic, rubber, art paint, and camouflage coatings, etc.

Tapping hole is mainly used in special steel smelting, skateboarding and large incinerator can be used for ceramic and color, rubber color, high temperature r coating, the fine arts in paint, ink for the preparation of printing money and securities. Chrome oxide green color similar to chlorophyll, can be used to camouflage paint, can make it difficult to distinguish infrared photography. Also a large number of used in metallurgy, refractory, abrasive powder. Also can be used as a catalyst in organic synthesis, it is the advanced green paint.

Pigment grade chrome oxide green series produced calcined chromium anhydride way a chrome oxide green product, product stability is strong, aging, widely used in floor, building materials, camouflage etc, it is a high grade inorganic pigment.

Ceramic grade chrome oxide green is high temperature calcination burn ways to produce a product of chromic anhydride, strong product tinting strength, high thermal stability, it is mainly used for ceramic glaze and other ceramic industry, foreign mainly exported to Italy, Spain and other countries. Thermal stability, not less than 1200 degrees.

Refractory grade chrome oxide green is calcined ways to produce a product, chromic anhydride product melting point of 2300 degrees Celsius, is mainly used for refractory material to add, and magnesite chrome brick making and other industries.

Chrome oxide green use instructions

Health hazard: 1, 3 +) on the nose, throat and skin damage, 6 chromium to stimulate the nose, throat, skin and eyes.

With soap and water 2, skin contact: rinse for 5 minutes.

3, the eye contact: flush with large amounts of water for at least 15 minutes, go to a doctor.

4, inhalation: remove the patient to fresh air, oxygen, or perform artificial respiration.

5, emergency handling: must wear protective gear into the field, using the simple method collect powder leakage and airtight container.

6, storage precautions: store in an airtight container, in a cool, ventilated place or places, avoid taboo.
