Latest company news about What Is The Difference Between Special Ceramics And Ordinary Ceramics?

Special ceramics refers to ceramics with special mechanical, physical or chemical properties, which are used in various modern industries and cutting-edge science and technology. The raw materials used and the required production technology have been greatly different and developed from ordinary ceramics. The country calls it "fine ceramics", and recently our country's material experts agree that it is called "advanced ceramics". Special ceramics can be subdivided into structural ceramics, functional ceramics and tool ceramics according to their performance characteristics and uses.

Different raw materials: In terms of raw materials, it breaks through the boundaries of traditional ceramics with clay as the main raw material. Special ceramics generally use oxides, nitrides, borides, carbides, etc. as the main raw materials.

 

The composition is different. The composition of traditional ceramics is determined by the composition of clay, so ceramics from different origins and kilns have different textures. Since the raw materials of special ceramics are pure compounds, the ingredients are determined by artificial proportions, and their properties are good and bad. The purity and craftsmanship of the raw materials are not affected by the origin.

 

Different structures: traditional ceramics have many impurities and pores, while special ceramics have excellent properties in terms of hardness, strength, corrosion, and wear.

 

The production process is different: it breaks through the boundaries of traditional ceramics and kilns as the main production methods, and widely adopts vacuum sintering, hot pressing, isostatic pressing and other methods.

 

Different properties: traditional ceramics are mainly based on life, and special ceramics have different special properties and functions, such as high strength, high hardness, corrosion resistance, electrical conductivity, insulation, as well as in magnetism, electricity, light, sound, biological engineering, etc. It has special functions, so that it has been widely used in high temperature, machinery, electronics, aerospace and medical engineering.
