High purity White aluminum oxide is a kind of middle or high level refractory material. With the eye-catching white color and the advantage of high density and low micro porosity, it can effectively improve the volume stability and the thermal shock resistance of the material. It is the mainly raw material to produce middle or high level unshaped or shaped refractory material. It is applied to the unshaped refractory materials, such as refractory carstables for ladles, middle or high level iron runner casting material, gunning refractory and fabricate parts ect. Cát Nhôm Oxit được nhập trực tiếp từ nước ngoài đạt tiêu chuẩn Châu Âu, độ tinh khiết cao. Kích thước hạt cát đồng nhất, chịu nhiệt, kháng sốc ở nhiệt độ cao.

Mô tả chi tiết sản phẩm
