Brown Aluminum Oxide P Grains Introductionï¼? Brown Aluminum Oxide is made by electric arc furnace smelting under high temperature with the raw materials of bauxite, anthracite and scrap iron. The significant chemical composition of brown aluminum oxide is aluminum trioxide (chemical formula: AL2O3). It is characteristic by high hardness, high toughness, and high abrasion resistance. The brown aluminum oxide P grain has more aggregative in distribution than F grain, with features of sharpness and evenly distributive, brings more efficiency for surface treatment. Brown fused aluminum oxide P grain is widely used in coated abrasive such as abrasive cloth, abrasive paper abrasive belts, etc.

Introduction white corundum: The raw material of white corundum is AL2O3. The production process is that after the alumina is smelted into a block in a high temperature furnace by a high temperature, it is broken into small pieces by a jaw crusher, and then crushed by a ball mill for secondary crushing, magnetically removed and then sieved into various models. The micropowder needs to be pickled and removed. White corundum has high purity, good self-sharpness, low calorific value, strong grinding ability, and good corrosion resistance. It has higher hardness than brown corundum, but it has no toughness of brown corundum. White corundum characteristics: 1. High alumina content and high hardness 2. self-sharpening, acid and alkali corrosion resistance 3. high temperature resistance, stable thermal performance, 4. Strong grinding ability, low heat generation and high efficiency.
