heat resistant Si3N4 Silicon Nitride Ceramic Tube bush pipe
Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
The mineral components of plastic raw materials are mainly clay minerals, which are all layered silicates, and their particles are generally minerals with a fineness below (<10μm) and a certain degree of plasticity. Such as kaolin, multi-water kaolin, bentonite, china clay, etc. Plastic raw materials mainly play the role of plasticization and bonding in production. They endow the billet with plasticity and grouting forming properties, ensuring the strength of the dry billet and various use properties after firing, such as mechanical strength, thermal stability, and chemical stability. They are The foundation for forming is also the foundation of clay ceramics. The mineral components of barren raw materials are mainly non-plastic silicon and aluminum oxides and oxygen-containing salts. Such as quartz, opal pyrophyllite, clinker after calcining clay, waste porcelain powder, etc. Barren raw materials play a role in reducing viscosity in production, which can reduce the viscosity of the blank. After firing, part of the quartz is dissolved in the feldspar glass to increase the viscosity of the liquid phase and prevent high-temperature deformation. After cooling, it acts as a skeleton in the porcelain blank.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
