Tabular Alumina
| Product Description |
Tabular alumina is pure-alumina resulting from intensive sintering at temperatures exceeding 1,800 °C, without sintering additives. Low temperature expansion and high heat resistance can be explained by the microstructure specifics: low effective porosity and large sizes of crystals with closed spherical pores resulting from intensive sintering.
| Application |
1.Tabular alumina can be used in various refractory alumina.
2.Tabular alumina can be used in unshaped refractories.
3.Tabular alumina can be used for precision grinding, such as measuring tools, instruments and apparatus parts.
