Tabular Alumina

1.Sintered alumina Sintered alumina is also called sintered corundum. It is a refractory clinker made of calcined alumina or industrial alumina powder as raw material, finely ground into balls or green bodies, and sintered at a high temperature of 1750-1900°C. Sintered alumina with a W(Al2O3) over 99% is mostly made of uniform fine-grained corundum directly

As a large-scale important raw material of refractory materials, tabular corundum is produced by using a high-temperature shaft kiln to produce sintered tabular corundum, which is characterized by the following process steps. 1. Ball milling. Using Bayer process light-burned alumina powder as the raw material for continuous ball milling, the fineness and specific surface area

The properties of tabular corundum have many applications in the field of refractories. Mainly used in the steel industry. Tabular corundum is an ideal material containing 90% alumina for high alumina bricks and amorphous linings. Tabular corundum is suitable for ceramic, chemical and water-bound substrates. Plate corundum can be used alone and in combination, or

Tabular corundum is a pure, sintered corundum that is fired without adding any additives such as MgO, B2O3, etc. It has a coarse, well-developed α-Al2O3 crystal structure, and the content of Al2O3 is more than 99%. So what are the applications of tabular corundum? The editor of Henan Sicheng provides detailed answers for everyone. Plate-like

The color of the slab corundum is white. In many cases, the quality of the slab corundum can be known only by observing the color of the slab corundum. However, many customers will find that sometimes it is inevitable that the tabular corundum will appear black or blue particles. So what is the reason for
