Why choose ZALY alumina powder
1) ZALY alumina powder is made from Australia imported high-purity raw material. It's calcined under high temperature(1420-1450 celsuis degree). The tranformation rate is 95% 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.
