Ceramic electronic components:
Advanced ceramics is a general term for pottery and porcelain. It is an inorganic compound material formed of metals and non-metals. Its performance is hard and brittle, and it has higher temperature resistance, corrosion resistance and wear resistance than metal materials and engineering plastics.
Modern special ceramics have more properties such as high strength, high hardness, corrosion resistance, conductivity, insulation, magnetism, light transmission, semiconductors, and piezoelectric, ferroelectric, photoelectric, acousto-optic, superconductivity, etc. Ceramic materials have become modern engineering materials One of the three pillars.Ceramic material with ZrO2 as the main crystal phase. ZrO2 has a melting point of 2700 ° C, has three crystal forms of monoclinic, tetragonal and cubic, and its phase transition temperatures are 1100 ° C and 2370 ° C, respectively. The transition from the tetragonal system to the monoclinic system is accompanied by significant volume expansion.
Therefore, after firing, micro cracks will occur during the cooling process. Generally, CaO, MgO, Y2O3, etc. are used as stabilizers to make ZrO2 Partially stabilized zirconia (PSZ). Zirconia ceramics have high toughness, good wear resistance, high bending strength and excellent thermal insulation, and even their expansion coefficient is close to that of metal.Due to customer needs, XY has recently developed ceramic component products such as zirconia (ZrO2) series, si
