The crystal forms of Al2O3 are: α, γ, η, δ, θ, κ, χ and so on. When the external conditions change, the crystal form will change. In the Al2O3 variant, since the oxygen in α-Al2O3 (density 3.99g/cm3) is the most compactly packed, only α-Al2O3 (corundum) is stable, and other crystal forms are unstable. Transformed into

Alumina is a very chemically ionized substance with a high melting point, hardness and high chemical stability, especially it can maintain high hardness and strength at high temperatures, and this AlO is widely used. Used in metallurgy, machinery, chemical industry, electronics, medicine, aviation and national defense. Due to the ultra-micronization of alumina powder, its surface

White corundum is the most suitable raw material for obtaining alumina powder, but the first step is to destroy it to a certain extent through a drum destroyer. Considering that there are many impurities in the raw materials, pickling and water washing are needed after destruction to effectively remove the impurities. Even if it is

With the wide application of hard and brittle materials such as ceramics, glass and semiconductors in the fields of optics, aerospace, and microelectronics, more and more attention is paid to their precision and ultra-precision processing. The large abrasive grain white corundum has the advantages of high processing efficiency and good wear resistance. The large abrasive

In order to be able to produce high-quality alumina powder, we usually control its roasting temperature during the production process. The specific operation methods are as follows: 1. The oil supply temperature must be raised and controlled by constant temperature. An electric heater device is installed in the kiln oil circuit, and the oil volume

Alumina powder is the main raw material for abrasives such as white corundum sand. If the materials used to hold the alumina powder are not clean or the packaging is unqualified, impurities will enter the alumina powder, causing differential secondary pollution and affecting its use Effect, in order to make this product have a good

High-temperature alumina powder is a common chemical raw material. Generally, the color is pure white, but sometimes it will be light yellow. Then, what factors affect the chromaticity of high-temperature alumina powder? 1. Pay attention to moisture-proof during storage. If the product is damp, its chromaticity will also be affected. 2. Particle size and particle

High-temperature alumina powder is made of industrial aluminum hydroxide and bauxite, molecular sieve and grinding balls as raw materials, and is calcined in a tunnel kiln for a long time at high temperature. What effect will the excessive iron oxide content in the high-temperature alumina powder have on ceramic What? The most intuitive effect of

High temperature alumina powder is made of industrial aluminum hydroxide and bauxite, molecular sieve and grinding balls as raw materials. It is calcined in a tunnel kiln for a long time at high temperature. It has a high melting point, excellent mechanical strength, hardness, high resistivity and Thermal conductivity. It can be widely used in

Alumina powder will dissolve to a certain extent at a certain temperature. In fact, the solubility of the product is a physical property. What is the specific solubility? Let’s understand it together. The solubility letter s of the product indicates that the unit is “g/100g water”. Unless otherwise specified, solubility usually refers to the solubility
