​​alumina raw materials

The composition and application fields of tabular corundum. Tabular corundum is corundum that is not smelted in an electric furnace. It is made of smelted alumina (Al2O3 content of more than 85%), which is wet-milled into a 3-micron micro-particle slurry (a binder should be added during ball milling), and then pressed into various geometric shapes … Read more

Tabular alumina, also known as tabular corundum in China, is a pure, completely sintered alumina that is fired without any additives such as MgO and B2O3. The tabular corundum has a coarse, well-developed α-Al2O3 crystal structure. Since it is sintered at a temperature slightly lower than 2035℃, close to the melting point of Al2O3, the … Read more
