Ceramika aluminiowa are a widely used type of ceramic. Due to their superior properties, their use is becoming increasingly widespread in modern society, meeting both everyday and specialized needs. They are extensively used in coal-fired power plants, steel mills, smelting plants, machinery factories, coal mines, chemical plants, cement plants, and port terminals, in applications such as coal conveying, material conveying systems, pulverizing systems, ash removal, and dust collection systems—all in high-wear mechanical equipment. Different types of products can be provided to meet various specific requirements.

After alumina ceramics are sintered and cooled, the processing is not yet complete. Some products may not meet application requirements, so further processing is necessary, such as dimensional correction and polishing. This article explains several polishing methods:

1. Grinding using diamond or silicon carbide (harder than alumina) in progressively finer grades;

2. Glazing is required (suitable for products requiring very high surface smoothness);

3. Grinding and polishing using Al2O3 micro powder or diamond paste;

4. Grinding and polishing using laser processing and ultrasonic processing;

5. Surface processing using ion implantation. Ion implantation in ceramics complements existing toughening mechanisms and represents a further processing step for prepared ceramic products.

Alumina ceramics are a widely used type of ceramic. Due to their superior properties, their applications in modern society are becoming increasingly widespread, meeting both everyday needs and special performance requirements. Currently, alumina ceramics are classified into two types: high-purity and ordinary.
