Structural Properties Of Ceramic Hob
- Dec 22, 2017 -

Traditional ceramic materials are usually taken from the natural world, such as the soil in Jingdezhen, through mixing, forming and roasting to make various daily necessities. And modern high-technology ceramics, also known as special ceramics, its material is synthetic, such as silicon nitride powder, high purity. The products made with modern powder metallurgy have the properties of high hardness and high temperature resistance.

Materials can be divided into metal materials and non-metallic materials. Nonmetallic materials are also divided into inorganic and organic materials

No matter what material, its properties, such as melting point, hardness and electrical conductivity, mainly depend on the internal microstructure. Organic materials depend on weak molecular binding force, so the melting point is low and the hardness is small. Metal material is combined with metal bond, its binding force is stronger than molecular bond, but the covalent bond and ionic bond are weak, so the melting point and hardness are still not high. Hard alloys are used to connect hard phases such as WC. Their properties are between metal and ceramics. Ceramic materials mainly consist of ionic bonds and covalent bonds. Their binding force is strong electrostatic attraction or shared electron pair between positive and negative ions, so they have high melting point, high hardness, good insulation, chemical stability and oxidation. This is the reason why the ceramic material can be a cutting tool.
