Zirocnia Ceramics:

Among the common ceramic and metal sealing workpieces, the more mature ceramic metallization of zirconia ceramics. In applications requiring corrosion resistance, high temperature resistance and mechanical shock resistance, the mechanical strength, corrosion resistance and thermal shock resistance of alumina ceramics have certain disadvantages, such as ceramic insulated insulation pipes and ceramics at high temperature and corrosion resistance. In the field of packaging sensors, ceramic insulating materials with higher strength, higher thermal shock resistance and higher bending strength are required to replace alumina ceramics. At normal temperature, the impact toughness, flexural strength, insulation and corrosion resistance of zirconia ceramics are ideal materials, but zirconia ceramics will exhibit insulation with oxygen concentration imbalance when the temperature reaches 300 °C or higher. Declining characteristics. At present, silicon nitride ceramics are an ideal material to replace alumina ceramics for higher requirements. Silicon nitride ceramics have good heat resistance characteristics, and are directly decomposed at around 1870 ° C under normal pressure. The oxidizing atmosphere can be used up to 1400 ° C, and the actual mechanical strength exceeds 1200 ° C. The coefficient of thermal expansion is small (2.8-3.2)×10-6/°C; the thermal conductivity is high, it can reach 90W; it is resistant to thermal shock, and the thermal shock from 1000°C to room temperature will not crack.
