Cr2O3 Powder Chrome Oxide Properties

What is Meltblown Grade Chrome Oxide Granules Cr2O3 Powder ？
Chemical property
Chromium oxide is an orange-red solid with the formula Cr2O3, which is amphoteric oxide and soluble in acids and bases to form corresponding salts. Chromium oxide is a solid solution containing several metal oxides, with excellent high temperature and oxidation resistance at high temperatures.
Physical property
Chromium oxide particles have high melting points, density, good light transmission, and insulation properties. It has a melting point of 2265 ° C, a 5.2g/cm3 density, and a refractive index of 2.7 to 2.9. Chromium oxide exhibits good thermal stability and resistance to corrosion at high temperatures. It can be heated to greater than 1000 degrees C in the air without causing decomposition.

Electrical property
Chromium oxide particle has excellent electrical properties. Its resistivity is greater than 1000Ω·m. The dielectric constant is greater than 10. The breakdown voltage is greater than 25kV/mm is a good insulating material. In addition, chromium oxide can also be used as a conductive material, for example, in electronics, communications, and automotive.
Optical property
Chromium oxide particles have high light transmittance, and their light transmission range is very wide, from ultraviolet and infrared rays to X-rays and gamma rays. In addition, chromium oxide can also be used as a photoelectric material, for example, in solar cells, optical communications, and photoelectric sensors.

Catalyst
Chromium oxide particles can be used as catalysts. It has high activity and selectivity and is often used in hydrocarbon cracking, alkylation, and hydrogenation reactions. In the petrochemical industry, chromium oxide catalyst is one of the most commonly used catalysts, which can improve the efficiency and yield of petroleum cracking.
Optical material
Chromium oxide particles have high transmittance and refractive index, making them important applications in optical materials. It can manufacture high-performance optical components, lasers, light modulators, and spectral analyzers. In addition, chromium oxide can also be used as a window material and coating material to improve the performance and stability of optical devices.
Protective coating
Chromium oxide particles can be used as protective coating materials. They have high hardness, wear resistance, and high corrosion resistance, which can protect the base material from corrosion and wear. For example, chromium oxide coatings in Marine environments can protect hulls, pipes, and equipment from corrosion and damage. In addition, chromium oxide can also be used as a high-temperature coating material to protect the material from high-temperature oxidation and corrosion at high temperatures.
Wear-resistant material
Chromium oxide particles have high hardness and wear resistance and can be used as wear-resistant materials. For example, adding chromium oxide particles to the material can improve its wear resistance and life when making mechanical parts. In addition, chromium oxide can also be used as a bearing material and sealing material to improve its wear and corrosion resistance.
Biomedical field
Chromium oxide particles are biocompatible and bioactive and can be used in the biomedical field. For example, chromium oxide can be used as a dental repair material with good aesthetics and wear resistance in the dental field. In addition, chromium oxide can also be used as a drug carrier and tumor treatment reagents to improve medical effects and safety.
