Low Sodium Boehmite for High Frequency Alumina Ceramics

Brief introduction--------Low Sodium Boehmite is the latest research achievement developed by our company, which is designed and manufactured by adopting foreign advanced technology. Using non-miner-alized catalyst as raw material, Low Sodium Boehmite (ALOOH) can be extracted through shrinking, dilution, crystal transformation dealkalization and purification under certain conditions. The characteristics of this product include: high chemical purity, low specific surface area, low pore volume, high bulk density, dense crystallization and high crystal phase purity, etc.

Because of its stable chemical purity, it is not easy to dissolve in acid-base solution. Its initial temperature for thermal decomposition is high, and under different high temperatures, it can be made into alumina product of non-mineralizsed low-sodium various crystal phase with multiple functions, which are widely used in the frontier industrial technology.

Specification---------

Characteristics---------

1.Small specific area: 1.5-2.0m2/g

2.Small pore volume: 0.05-0.10ml/g

3.Low sodium (Na2O): 0.02-0.03

4.High bulk density: 1.15-1.25lg/l

Main Applications---------

1.With stable physicochemical property, this product is often be used as high-temperature-resistant-flame-retardant filler currently.

2. Through calcination under different temperatures, this product can be made into non-mineralized alumina products of different crystal phases, which can be used as high-grade refractory materials, high-frequency alumina ceramics, high-energy battery, high-grade abrasive products, polishing material and electronic substrate.

3. It is also widely used in the field of high-speed ceramic cutting tool, etc., which cannot be substituted by other materials.
