High Heat Dissipation Alumina
High heat dissipation alumina has microporous adjustment effect. High heat dissipation alumina has a plate-like crystal structure.High purity alumina (Al2O3) is a white amorphous powder, insoluble in water, an amphoteric oxide, soluble in inorganic acids and alkaline solutions, and has five allotropes: amorphous alumina, α-Al2O3, β-Al2O3, δ-Al2O3, γ-Al2O3, mainly α-Al2O3 and γ-Al2O3. Among them, α-Al2O3 is the hardest and densest structure, and is most suitable for guest materials or ceramic applications. With the increase of temperature, all crystal forms of high-purity alumina can eventually be converted into α-Al2O3
Product Introduction
Product Introduction：
High heat dissipation alumina is a commonly used filler for composite thermally conductive materials, mainly because alumina has high thermal conductivity, good insulation properties, and stable physical and chemical properties.When the current is too large, the material heats up, and the plate-like crystal structure of high purity alumina coating material will expand in volume, which will close the current conduction hole on the lithium battery separator. So as to block the current.

Application characteristics:
High heat dissipation alumina is white micropowder with uniform particle size, easy to disperse, stable chemical properties, moderate high temperature shrinkage performance, and good sintering performance; high conversion rate and low sodium content.
High purity alumina has outstanding characteristics such as porosity, high dispersibility, insulation and heat resistance, and has been widely used in artificial crystals, fine ceramics, transparent ceramics, bioceramics, semiconductor integrated circuit substrates, etc. Generally, 3N high-purity alumina is mainly used for advanced ceramics, 4N high-purity alumina is mainly used for phosphors, and 5N high-purity alumina is used for sapphire crystals, lithium battery separators, advanced ceramics, PDP phosphors and some high-performance materials, etc.
