Product Description Product DescriptionSilicon Nitride Ceramic: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.Alumina ceramic 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.Detailed Photos Product ParametersPropertyUnitMaterialSi3N4 99.5% Al2O399% Al2O396%Al2O3ZrO2Densityg/cm3≥3.20≥3.90≥3.85≥3.65≥6.0Water absorption%-0000HardnessHV-1700170015001300Flexural strengthMpa≥600≥379≥338≥320≥1200Compressive strengthMpa≥2500≥2240≥2240≥2000≥1990Fracture toughnessMpa m1/264-54-53-46.5-8Max. service temperatureoC12001675160014501000Coefficient of thermal expansion (CTE)1×10 -6 /oC3.26.5~8.06.2~8.05.0~8.08.0~9.5Thermal shockT(oC)≥600≥250≥200≥220≥300Thermal conductivity(25oC)W/m.k203029243Volume resistivityohm.cm 25oC->1 x 10 14>1 x 10 14>1 x 10 14>1 x 10 11300oC-1 x 10 128 x 10 1110 12 -10 131 x 10 10500oC-5 x 10 102 x 10 91 x 10 91 x 10 6Insulation strengthKV/mm 19181817Dielectric constant(1Mhz)(E)69.79.59.529CertificationsPackaging & ShippingCompany ProfileYixing City is the famous pottery capital in China.
