Product Advantages: small particle size, uniform dispersion, less impurities

Boric acid acts as an additive in the alumina industry. It is mainly used in the production process of alumina firing Alpha alumina. Alumina is alkaline and contains sodium ions. Sodium oxide and boric acid react to form sodium borate. In addition to sodium, neutralize and increase wafer particle size.

The crystal form of alumina changes during high-temperature sintering, and the α crystal form is the most stable at 1400-1500°C.


Industrial boric acid plays an additive role in sintering production, and the general addition amount is 1%-1.5%. α-Alumina has uniform particle size distribution, high purity and high dispersion. It has a low specific surface and is inert to high temperature; it can be widely used in various rubber, ceramics, refractory materials, casting and other industries to strengthen and toughen. At the same time, the α-phase alumina has high resistivity and good insulation properties. In spark plugs and integrated circuit substrates.

The requirements of α-alumina for industrial boric acid in the market. In the sintering process, the finer the particle size of boric acid, the better the dispersion in alumina sintering and the better the sintering reaction effect. It can improve the conversion rate of crystal form, increase the grain size and stability of crystal form. In general, the industry uses Del's ultra-fine boric acid with a fineness of 120 mesh. The effect is best
