Product Description Product DescriptionProduct DestriptionCustomized high hardness Si3N4 silicon nitride ceramic industrial parts Silicon nitride ceramic is an inorganic material ceramic that does not shrink when sintered. Silicon nitride is very strong, especially hot pressed silicon nitride, which is one of the hardest substances in the world. It has high strength, low density and high temperature resistance. Si3N4 ceramic is a covalent bond compound. The basic structural unit is a [SiN4] tetrahedron. The silicon atom is located at the center of the tetrahedron. There are four nitrogen atoms around it, which are located at the four vertices of the tetrahedron, and then every three A tetrahedron shares the form of an atom, forming a continuous and robust network structure in three dimensions.High strength over a wide temperature rangeHigh fracture toughnessHigh hardnessOutstanding wear resistanceGood thermal shock resistanceGood chemical resistanceCompany InformationFactory ShowOur ProductsCeramic Properties PropertiesUnits96%Al2O399%Al2O3ZirconiaSiliconNitrideMachinableCeramicMaterial Characteristics Gas Permeability 00000Water Absorption %0%0%0%0%0.038%Colour WhiteIvoryWhiteGreyWhiteDensity g/cm33.73.8563.22.7Physical Characteristics Hardness Kg/mm211001400110016001175Modulus of Elasticity Gpa30035020030065Flexural Strength Mpa3003401150600108Compressive Strength Mpa2100220025002500488Fracture Toughness Mpam1/23.54126 Thermodynamic Property Max Use Temperature °C1500165015001800800Thermal Conductiviey W/(m.k)2527.52.5201.68Thermal Expansion Coefficient 10-6/°C7.58103.28.6Thermal Shock Resistance △T°C200200250600200Specific Heat J/kg.K860860500500 Electrical Specification Dielectric Strength KV/mm12105 40Dielectric Constant εr9.59.11267Volume Resistivity Ω≥1014≥1014≥1010≥1014≥1016Dielectric Loss Angle 0.00020.00020.001 Packing & Delivery Why Choose Us? 1.12 years of professional production industrial ceramics factory2.
