Green Chrome Oxide-Adding Splendid Color for Living



Chrome oxide, with the chemical name of Cr2O3 has various colors varing from bright green to dark green. Presenting within the form of crystal power, it has the density of five.21, fusing point at 2266?? and boiling point at 4000??. With metal luster, magnetism and fantastic covering power, chrome oxide nonetheless has performances of high temperature resistance and insolation resistance. It is insoluble in water and hardly dissolvable in acid. Also, it keeps steady within the air to ensure that it has no effect on gases like acid alkali, sulfur dioxide and hydrogen sulfide. Chrome oxide plays an essential role in Inorganic Pigment field by its excellent and prominent pigment property and sturdiness as well as the high covering power and color saturation.
At present, green chrome oxide is primarily applied in smelting chromium metal and chromium carbide. It's also applied in material dying like enamel, ceramics, glass, artificial leather, fireproof material and construction material. Besides, it's used in organic compound catalyst and manufacturing sun-proof material, unique ink for printing paper, grinding material by metal polishing, metal facial chromizing and magnetic material. Nowadays, most green chrome oxide is applied in metallurgy, manufacturing chromium metal and chromium alloy, refractory material and grinding powder. For the reason that it has comparable plants chlorophyll, it can also be utilized in camouflage paint which makes it indistinctive in infrared mapping. Therefore, it was ever applied in weapon defend coating within the military.
Ceramics tiles manufacturing enterprises commonly seldom directly apply green chrome oxide. The reality is the fact that the ceramic pigment applied contains component of green chrome oxide that is generally called Chrome Green Ceramic Pigment. The frequently seen selection of ceramic paintings containing green chrome oxide consists of peacock blue, peacock green, navy blue, navy green, grass green, black, coffee, orange, cream colored, reddish brown, golden yellow and others. Basically most ceramic pigment contains the element of green chrome oxide. Definitely it is the exception for zirconium series products.
Today, with higher technologies developing rapidly, coating brings fantastic splendidness to our living. Most people understand that coating is diversified in colors and types. The mainly often contacted coating includes fireproof coating, water based paint, solvent based coating and all the like. Behind the coating of all sorts, we can't but to mention their primary compound paint raw material, green chrome oxide. As a type of main colour development and color auxiliary additive, Fused Chrome Oxide is widely applied in most ceramic pigment.
In ceramic industry, application quantity of green chrome oxide is same incredible. Based on incomplete statistics, the amount green chrome oxide applied in ceramics and the associated assorting enterprises each year reaches tens of tons. Essentially, so long as it's a ceramics enterprise, there directly or indirectly applies green chrome oxide. Especially in chemical material needed by pigment enterprises, green chrome oxide occupies a large proportion. Commodity green chrome oxide is mostly directly or indirectly manufactured from sodium bichromate whose yield appropriately occupies 20 percent of total sodium bichromate consumption having a sound chromium oxide cost.
