The main differences between fine ceramics and traditional ceramics

 

1. In terms of raw materials, it breaks through the boundary of traditional ceramics using clay as the main raw material. Special ceramics generally use oxides, nitrides, silicides, borides, carbides, etc. as the main raw materials.

2. In terms of composition, traditional ceramics are determined by the composition of clay, so ceramics from different regions and kilns have different textures. Due to the fact that the raw materials for special ceramics are pure compounds, their composition is determined by manual proportioning, and the quality of their properties is determined by the purity and process of the raw materials, rather than by the place of origin.

3. In terms of preparation technology, it has broken through the boundaries of traditional ceramic production methods mainly using furnaces and kilns, and widely uses vacuum sintering, protective atmosphere sintering, hot pressing, hot static pressing and other methods.
