![]() ![]() Tabular corundum is a kind of pure sintered corundum with complete shrinkage without adding any additives such as MgO and B2O3. High fire resistance High corrosion resistance High erosion resistance High thermal shock stability High strength and good toughness Stable chemical properties. The refractory or castable used for production has good thermal shock stability and bending strength after high-temperature treatment, but the price is higher than that of other alumina. It has high purity, good volume stability and minimal reheating shrinkage. The plate-like crystal structure has small pores and many closed pores, and the porosity is roughly the same as that of fused corundum. Tabular corundum is a kind of pure sintered corundum with complete shrinkage without adding any additives such as It has the characteristics of coarse crystal and good development crystal structure. Tabular Alumina: The plate-like crystal structure has small pores and many closed pores, and the porosity is roughly the same as that of fused corundum. Refractories in Ceramic, Glass, Cement Industries Ladle Pouring Material, Sliding Nozzle, Prefabricated Parts in Steel Making Industry It's used in many process of steel making industry and also used in ceramic, metallurgical, glass industries.Ĭoefficient Expansion Indexï¼?0-1600 degree ): 7-9 Tabular Alumina we supply has very good particle distribution and is very clean. After sintered, the aluminum oxide is well crystalized and has high density, low porosity and stable volume. It's high temperature resistant, corrosion resistant, anti heat shock, tough, stable in chemical content, good in heat conductivity. Tabular Alumina is a high purity sintered alumina for refractories with Aluminium Oxide(Al2O3) more than 99.8%. Chemical & typical physical propertiesĤ, supply all the size 8-5mm, 5-3mm, 3-1mm, 1-0mm, -325mesh It can replace fused alumina and white fused alumina in some application position, and improve the performance of refractory material.Ĥ. Tabular alumina is the perfect refractory raw material, which is widely used as the aggregate for producing various alumina refractory, it also can be used in other monolithic refractory. Tabular alumina is characterized by good heating volume temperature performance and good thermal shock resistance. But the price is higher than the other alumina. After high temperature treatment, tabular alumina is used for refractory and castable characterized by good thermal shock stability and flexural strength. The tabular crystal structure is characterized by narrow pores, with more closed porosity, almost the same apparent porosity compare with fused corundum, high purity, good stability volume density, tiny refiring shrink. They are produced in electric arc furnaces by electrofusion at temperatures around 2000☌.White tabular alumina is a kind of pure sintered corundum, which is sintered and completely shrink without adding any additive, such as mgo or b2o3, with coarse crystals and well-developed alpha al2o3 crystal structure. It is ideal for injection moulding, extrusion or slip casting and features an overall high product consistency including carefully controlled particle size distributions.įused aluminum oxides are synthetic hard minerals based on α - aluminum oxide. Under our flagship ALODUR brand of fused alumina, we offer a variety of grades and sizes, such as our 99% White fused alumina, to suit a wide range of applications. It can also be joined to metals or other ceramics by metalizing or brazing. Many ceramic processing methods can be applied, such as net shape forming or machining to produce a wide variety of shapes and sizes of components. As the most widely used material in many ceramic applications, either in a pure form or in alumina containing material, it can be supplied in a range of purities, with additives if required, designed to enhance properties. ALODUR fused alumina for advanced ceramic applicationsĪlumina and advanced ceramics go hand in hand. ![]()
