SUOYI High Purity 99.99% Nano Alumina Powder White Powder Al2O3 CAS 1344-28-1 Use for Mlcc
Aluminum oxide is an inorganic substance with the chemical formula Al2O3. It is a high-hardness compound with a melting point of 2054°C and a boiling point of 2980°C. It is an ion crystal that can be ionized at high temperatures and is often used to make refractory materials.
Alumina is a stable oxide of aluminum with the chemical formula Al2O3. It is also called bauxite in mining, ceramics and materials science.
Properties: White solid that is difficult to dissolve in water, odorless, tasteless, extremely hard, easily absorbs moisture but does not deliquesce (it does not absorb moisture after burning). Aluminum oxide is a typical amphoteric oxide (corundum is α-shaped and belongs to the hexagonal closest packing. It is an inert compound, slightly soluble in acid and alkali and resistant to corrosion). It can be soluble in inorganic acids and alkaline solutions, and is almost insoluble in water. And non-polar organic solvents; relative density (d204) 4.0; melting point 2050°C.
Storage: Store in a sealed and dry container.
Usage: used as analytical reagents, dehydration of organic solvents, adsorbents, organic reaction catalysts, abrasives, polishing agents, raw materials for smelting aluminum, and refractory materials
Phone screen polish, including the final polishing for sapphire cell phone screen, cell phone glass screen. Can also be used: artificial gems, zircon, high-grade glass, natural stones, jade, agate and other vibratory finishing (machine polishing, roll polishing), manual polishing (grind polishing)etc.
Metal polishing, including mobile phone shell, car wheels, high-grade hardware final polishing. It can also be applied to aluminum, copper, stainless steel, stone, tiles and other polishing.

Spherical alumina is prepared by laser flame jet fusion method, with small specific surface area, clean surface, no residual impurities, easy to disperse, high sphericity rate, high content of α-phase alumina, etc. High filling ability, high particle sphericity, narrow particle size distribution, high density filling of rubber and plastic, low viscosity, good fluidity mixture can be obtained. High thermal conductivity, because it can be filled with high density, compared with crystalline sillicon, it can obtain a mixture of high thermal conductivity, good heat dissipation, and low abrasion. Because of its spherical appearance, it is suitable for mixers, molding machines and molds, the wear and tear is greatly reduced, which can extend the service life of the equipment.
γ-Al2O3 nanopowder was made at 500~700℃, and is of uniform distribution of particle size, high purity, high specific surface area, thermostability, high activity. γ-Al2O3 is the mean of catalyst support, and material for petrochemical industry, environmental protection etc.
