ZALY Activated Alpha Alumina Powder
1) 98.6% min high purity, raw material origin is Australia
2) SGS, ISO audited manufacturer
3) mass production ability
4) stable chemical features with extremly fine particle size
5) hot-selling in east asia market with favorable price
Why shoose ZALY activated alpha alumina powder
1) ZALY activated alpha alumina powder is made from Australia imported high-purity raw material. It's calcined under low temperature(1380 celsuis degree). The tranformation rate is 93% min.
2) It is produced by the general international law of Bayer, calcined by boron free rotary kiln, washed by water to remove sodium.
3) All these technical method can greatly improve the product quality, purity and stability, and the bulk density of ceramic products, mohs hardness and ability to withstand voltage, etc.
4) ZALY are located in Lianyungang imp$exp tax-free zone, we enjoy the exclusive alumina powder imp&exp rights in China.
Technical features:
1) excellent chemical activity
2) extremely fine particle size (D50=0.05~0.08 um)
3) low water absorption rate, big true density
4) wear-resistant, heat-resistant, corrosion resistant
Applications:
1) It's especially suitable for manufacturing shaped products.
2) It is widely used in manufacturing monolithic refractory materials such as: Refractory castables, plastics, reparing mix, gunning materials, coating materials etc.
3) It can greatly improve the corrosion-resistance, heat-resistance and thermal shock resistance of these refractory materials.
