The spots in the abrasion resistant ceramic not only affect the appearance of the product, but also affect its abrasive performance, Therefore, in the production process of ceramic parts, it needs to be strictly controlled. However, due to the limitations of production equipment and production conditions, and people's inconsistent understanding of the causes of spots, product spot defects occur from time to time, and sometimes the proportion is relatively high.

1.Preliminary analysis of the elements and components that form spots

According to the characteristics of the Al2O3 ceramic raw materials and the process equipment of the processed products in the manufacturing industry, on the one hand, the original minerals contain substances that form spots; on the other hand, the metal materials that the raw materials may contact, generally carbon steel and stainless steel, preliminary analysis These metal materials are the cause of spots

2:Analyze the causes of spots during the ceramic production process

The ferromagnetic impurities adsorbed in each process stage can cause  Al2O3 ceramics to form spots during the firing process. 

Chemshun seriously recognized the spot bad influence. And pay much attention to the spots avoidance during production. Hope we can serve customer with better ceramic quality
