Advanced ceramic materials, also known as precision ceramic materials, refers to the use of refined high purity, ultra-fine inorganic compounds, manufactured by raw materials and advanced preparation process techniques. According to engineering technology, the product is required for product use performance, and the manufactured products can have piezoelectric, ferroelectric, conductive, semiconductor, magnetic or other or high strength, high tough, high hard, wear resistance, corrosion resistance, high temperature, high thermal conductivity, Excellent properties such as adiabatic or good biocompatibility.
