Pure White Hexagonal Boron Nitride Ceramic
Pure White Hexagonal Boron Nitride Ceramic is a composite material made of boron nitride powder and composite powder sintered by hot pressing. It is a kind of hexagonal crystal with phosphorus sheet structure, with special physical and chemical properties, and is a new type of inorganic non-metallic material.
Description
The boron nitride powder is loose, lubricating, light in quality, and easy to absorb moisture. The color is white, and the products are ivory white.
Pure White Hexagonal Boron Nitride Ceramic has high strength, good toughness, high thermal conductivity, low thermal expansion coefficient and strong corrosion resistance. It can be easily processed into various precision shapes, such as crucibles, casting nozzles, horizontal continuous casting broken rings, etc.
Areas of application
Pure White Hexagonal Boron Nitride Ceramic are widely used in various fields, including electronics, aerospace, nuclear energy, and metallurgy.
One of the most important applications of BN ceramics is as a high-temperature insulator in electronic devices. Due to its excellent thermal conductivity and resistance to electrical breakdown, BN ceramics can be used as a substrate for electronic components, such as transistors and diodes. It can also be used as a heat sink and thermal management material in high-power electronics.
In the aerospace industry, BN ceramics are used as a thermal protection material for space shuttle tiles and rocket engine nozzles. BN ceramics have a high melting point and are resistant to oxidation, making them ideal for use in extreme environments. They are also used as a lubricant in the aerospace industry, as they have a low coefficient of friction and do not react with other materials.
In the nuclear energy industry, BN ceramics are used as a radiation shield. They are highly resistant to radiation and can be used to protect nuclear reactors and other sensitive equipment. BN ceramics are also used in the metallurgy industry as a mold release agent, due to its non-stick properties.
Overall, the advantages of BN ceramics include high thermal conductivity, excellent chemical and thermal stability, and resistance to oxidation and radiation. They are essential materials in various high-tech applications, and their ongoing development and use will continue to enhance our modern technologies and improve our quality of life.
