Zirconia ceramic tubes are made from pure zirconia powder by high-temperature sintering. Zirconia (ZrO₂) is usually a white, odorless and tasteless crystal with a relative density of 5.85, a melting point of 2680°C, a boiling point of 4300°C and a hardness second only to diamond. It is chemically stable and has a high melting point, high resistivity, high refractive index and low coefficient of thermal expansion. Because of these characteristics, zirconia ceramic tubes play an important role in many fields. The main component of boron nitride tubes is boron nitride (BN). Boron nitride has a variety of crystal types, and the common hexagonal boron nitride ceramic structure is similar to graphite, known as ‘white graphite’. With their unique crystal structure, boron nitride tubes exhibit a range of excellent properties and are widely used in specific fields.
