Boron nitride ceramic threaded tubing exhibits excellent high-temperature resistance and good chemical stability, maintaining a stable structure even under high-temperature environments and resisting cracking and deformation. It also possesses good electrical insulation, corrosion resistance, and thermal shock resistance, making it suitable for applications with frequent temperature changes. Furthermore, the material has excellent self-lubricating properties, preventing adhesion of molten metal, making it suitable for use in high-temperature precision equipment.
The expansion coefficient of hexagonal boron nitride is equivalent to that of quartz, but its thermal conductivity is ten times that of quartz. It also has good lubricity at high temperature. It is an excellent high temperature solid lubricant. It has strong neutron absorption capacity, stable chemical properties, and is chemically inert to almost all molten metals.
Feature
Lower density: 2.27g/cm，Lower than most ceramics High thermal conductivity: the thermal conductivity of hot pressed products is 33W / M.K, which is the largest among ceramic materials above 530 ℃. Low thermal expansion coefficient: 2×10-6 is the smallest expansion coefficient in ceramics, next only to quartz glass The lower friction coefficient: U is 0.16 and does not increase at high temperature Good corrosion resistance: no chemical reaction with general molten metal Toxicological safety
