Why is chrome oxide so stable?
What is chromium oxide?
Chromium oxide is a cubic crystal system or amorphous green powder with two color phases: light olive green and dark olive green with a metallic luster. Relative Density5.21.Melting_ point2266℃.Boiling_ Point 4000 ℃. It has excellent heat resistance, can withstand 1000 ℃ without discoloration, and has excellent acid and alkali resistance. It is insoluble in water, insoluble in acid, and soluble in hot alkali metal bromate solution. It is extremely stable to the light, atmosphere, sulfur dioxide, hydrogen sulfide, and other corrosive gases. It has a very high hiding power, but its coloring power is not as good as phthalocyanine green. The color is not bright enough, the particle size is hard, and the gloss of the paint is slightly poor. It is magnetic and toxic.
Use of chromium oxide
It is mainly used for special steel smelting tap holes, slide plate mouths, and large incinerators, which can be used for coloring ceramics and enamel, rubber coloring, preparing high-temperature resistant paint, painting pigment, and preparing printing ink for paper currency and securities The color of chrome oxide green is similar to that of plant chlorophyll. It can be used as camouflage paint, making infrared photography difficult to distinguish. It is also widely used in metallurgy, refractory materials, and grinding powder. It can also be used as an organic synthesis catalyst and is a high-grade green pigment.
The Harm of chromium oxide to human body
Chromium compounds do not damage intact skin, but they can cause injury due to skin abrasion when exposed to chromium compounds. The incidence rate of chronic skin ulcers is relatively high, mainly related to the length of contact time, skin allergy, and personal hygiene habits. Chromic ulcers mainly occur in hands, arms, and feet but can occur wherever the skin is damaged. The nail's root is the exposed area, which easily accumulates dirt, and the skin is also the most vulnerable to damage, so these areas also easily form chrome sores. Before the formation of chrome sores, the skin initially appears red and swollen, with a sense of itching, and can invade deep without proper treatment. The ulcer is covered with a hard scab of secretions. The surrounding part is raised, the center is deep and full of carrion, the edge is obvious, grayish red, local pain, the ulcer is inverted cone, the ulcer surface is small, generally not more than 3mm, sometimes it can be as large as 12-30mm, or as small as the size of a needle tip. If the treatment is ignored, it can be placed deep into the bone for further development, severe pain, and slow healing.
Price of chromium oxide
Chromium oxide particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of chromium oxide. A large amount of large amount will be lower. The Price of chromium oxide can be found on our company's official website.
