The continuous research of modern technology on ceramic materials has made ceramics not only used in living utensils, but also used in all aspects of life such as mobile phone backplanes, sensor substrates, circuit board substrates, and so on。
New ceramic materials have their unique advantages in performance. In terms of thermal and mechanical properties, there are high temperature resistance, heat insulation, high hardness, wear resistance, etc.; in terms of electrical properties, there are insulation, piezoelectricity, semiconductivity, magnetism, etc.; in terms of chemistry, there are catalysis, corrosion resistance, and adsorption. And other functions; in biology, it has certain biocompatibility and can be used as biological structural materials. Therefore, the research and development of new functional ceramics is an important field in materials science.
Zirconia ceramics is one of the most widely used new ceramic materials. It is made by adding zirconia (ZrO2) to the ceramic production of the new process. Its excellent high temperature resistance is used as induction heating tubes, refractory materials and heating elements. At the same time, zirconia ceramics have the advantages of high toughness, high bending strength and high wear resistance, excellent thermal insulation performance, and thermal expansion coefficient close to steel. Therefore, they are widely used in thermal barrier coatings, catalyst carriers, medical treatment, health care, etc. Refractory materials, textiles and other fields。
Piezoelectric ceramics are functional ceramics that can convert pressure into electrical energy. Even the slight pressure generated by sound wave vibration can cause them to deform, thereby charging the ceramic surface. The gas electronic lighter made of ordinary flint is replaced by piezoelectric ceramic column, which can continuously fire tens of thousands of times。
