Zirocnia Ceramics:

Zirconium oxide ceramic structural ceramics include ceramic materials such as abrasion resistance, high strength, heat resistance, thermal shock resistance, hardness, high rigidity, low expansion and heat insulation; functional ceramics include acoustic, optical, electrical, magnetic, biological, Ceramic materials with functions such as chemistry and nuclear. The basic physical properties of Si3N4 Under normal pressure, si3N4 has no melting point. The thermal expansion coefficient of silicon nitride directly decomposed at around 1870 °C is low. In addition to SiO2 (quartz) in ceramic materials, the thermal expansion coefficient of Si3N4 is almost low. 2.35×106/K, which is about 1/3 of A1203, its thermal conductivity is large, 18.4W/(m·K), and it has high strength, so its thermal shock resistance is very good, second only to quartz. And glass-ceramic, the thermal fatigue performance is also very good. The room temperature resistivity is 1.1x10"Q·cm, 5.7×106Q·cm at 900C, the dielectric constant is 8.3, and the dielectric loss is -0. 1. Silicon nitride ceramic material has excellent thermal stability, strong oxidation resistance and high product size. Since silicon nitride is a covalent compound with high bond strength and can form an oxide protective film in air, It also has good chemical stability. It is not oxidized below 1200 °C. The protective film formed at 1200~1600 °C can prevent further oxidation and is not covered by many kinds of molten metals or alloys such as aluminum, lead, tin, silver, brass and nickel. Infiltrated or corroded, but can be melted by magnesium, nickel-chromium alloy, stainless steel, etc. Eclipse.
