What factors affect the chroma of high temperature alumina powder

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 size distribution: When producing high-temperature alumina, it is necessary to prepare a suitable particle size and particle size distribution, otherwise the chromaticity of the product will be affected.

3. Raw materials: The color of the product is directly related to the raw materials. If the selected raw materials are stable, pure, and high-quality, the produced product will be more shiny. If the poorer raw material is selected, the produced product will change. It’s gray and has no luster.

What are the crystal forms of alumina powder

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
