Parameter
Our AW series of reactive α-Al₂O₃ micropowder is manufactured to corporate standards exceeding those of renowned international alumina micropowder producers. Utilizing a unique production process, the product achieves low impurity content, controllable sintering activity, fine grain size, and high phase transformation rate, making it a vital raw material for producing high-quality refractory materials.
When used in castables, it exhibits excellent flowability, low expansion, extended working time, high intermediate-temperature strength, dense structure, and excellent performance.
Note:
Particle size can also be processed according to customer requirements.
For other special performance requirements, please contact us for customized production.
Minimum order quantity: 1 ton.
