Black aluminum oxide 0-1, 1-3, 3-5, 5-8mm for wear-resistant pavement
Black aluminum oxide is a gray-black crystal with Al2O3 and iron spinel as the main ore phase, made of high alumina bauxite, high iron bauxite or iron oxide scrap, smelted at high temperature in an electric arc furnace.
It has good wear-resisting and anti-slip performance.
Black aluminum oxide section sand 0-1mm, 1-3mm, 3-5mm, 5-8mm is applicable to lay the steep slope of the wear-resistant anti-skid pavement, bridge deck, parking lot.
