Introduction to the properties and characteristics of alumina ceramics

Introduction to the properties and characteristics of alumina ceramics

Alumina ceramic is an industrial ceramic with high hardness that can only be processed by diamond grinding. It is made of bauxite and can be processed using injection molding, pressing, isostatic pressing, sliding casting, etc., then Pintejin ceramics Let us introduce the properties and characteristics of alumina ceramics.

Properties and Characteristics of Alumina Ceramics

Using high-purity sub-μm aluminum oxide ultrafine powder, it is possible to produce aluminum oxide high-precision ceramic raw materials with a tensile strength of 700-1000Mpa and a Weber displacement coefficient of 40. However, the impact toughness of such raw materials is extremely low. Generally only 3 ~ 4MPa.m.

Therefore, improving the impact toughness of alumina ceramics has always been the general goal of the hope and diligence of ceramic raw material biologists. Under normal conditions, the net weight ratio is 10-30% of thermosetting plastic or epoxy resin.

The organic chemical binder should be uniformly mixed with the alumina powder at a temperature of 150-200 degrees Celsius to facilitate the actual operation of forming. If the press forming method is selected, no adhesive is required for the raw material of the powder equipment.

If the automatic or automatic dry pressing method is used, the powder equipment has good machining requirements, which must be solved by the sprayer plastic machining method.

The alumina ceramic products are displayed in a spherical shape, and it is also beneficial to improve the fluidity of alumina ceramic equipment and to automatically fill the mold wall during the whole process of powder equipment material forming.

The enhanced machining of alumina ceramics is a further improvement on this basis, not only in the whole process of product production, but also in the improvement of the pass rate of products. It has significant results! Today’s sales market.

Alumina ceramic materials have been seen in many cases. These materials use the chemical properties of air alumina, but do not integrate aluminum oxide and ceramics. The materials of this type of alumina ceramics are compared with other materials of the same channel. Both thermal properties and plasticity have great advantages.

The above are the properties and characteristics of alumina ceramics brought to you by Pintejin Ceramics.
