Factors affected the proerty of wear resistant ceramics (part 1)

                    ------------- the impact of the raw material powder

The main raw material of abrasion resistant ceramic is high purity AI23 powder,  which performance is good or bad, and how much alumina content the powder has  plan a great impact on the alumina ceramic ceramics . Impurities is inevitably introduced into ceramic powder during the manufacturing process . organic impurities are burned off in the firing process and formed into irregular holes ; and inorganic impurities in high-temperature phase is likely to react with the ceramic powder and the residual formed micro-cracks.  The densification defect  on microstructures caused by impurities has a significant impact on the ceramic liner itself, and therefore high purity AI2O3 powder is an important prerequisite for alumina ceramic liner with excellent performance   .

Typical wear-resistant ceramic production is purified from sintered alumina powder through many industrial processes  as raw material products according to the requirements, according to a certain formula powder mixed and then formed by molding and sintering processes. wear resistant ceramics thus produced has a very good performance, but because the whole process is longer, and therefore higher production costs.

In order to save costs, some wear resistant ceramics producer also directly use minerals as the main raw material, than adding a small amount of sintered alumina powder. Some people even use recycled scrap aluminum oxide ceramics as a main ingredient, which cann't formed an organic part with the surrounding molecules ɑ alumina ceramic s,combination of compactness and abrasion resistance greatly reduced. This is why the market is huge spread resistant ceramic one of the main.
