Boron nitride
A crystal made up of both boron and nitrogen. Its chemical makeup is 56.4% and 43.6% respectively. Boron nitride is available in four forms: hexagonal boron nitride HBN, diamond Square Boron Nitride RBN and Cubic Boron Nitride CBN.
Boron Nitride Properties
Boron Nitride is impervious to corrosion and inorganic acids, but not water. Hot concentrated alkali breaks down the boron/nitrogen bond and oxygen at 1200 degrees Celsius begins to react with it. Boron Nitride is slightly insoluble in hot acids, but insoluble when dissolved in cold water. It has a relative density of 2.25.
Many of the properties found in boron-nitride outperform those of carbon materials. The hexagonal boron-nitride has a low friction coefficient and good high temperature stability. It also exhibits high strength, high thermal resistance, and low electrical resistance.
Boron Nitride Applications
1. Hexagonal Boron Nitride has excellent chemical stability. This metal melt-resistant compound does not affect steel, stainless steel or bimetallic alloys like si, alfe, ge and bi. Boron nitride has many uses.
2. Hexagonal Boron Nitride is heat- and corrosion resistant. It can be used to make high-temperature components for rocket combustion chambers, spacecraft thermal shielding, as well as parts that resist corrosion in magnetic fluid generators. It can also be produced.
3. Hexagonal boron Nitride has insulating characteristics and is used widely in plasma arc and high voltage electricity, as well as heater sleeves, heat dissipators and various heaters.
4. This is used by the electronics industry to make gallium arsenide, indium phosphide and gallium trisenide. It also serves as heat sinks for heat shifters and semiconductor package heatsinks.
5. It’s used to absorb neutrons and protect them in an atomic reactor. It is also used in infrared, microwave, filter, laser path instrument and ultra-high pressure pressure transmission materials.
6. Hexagonalboron nitride can also be used to lubricate high temperatures and as an integral part of self-lubricating gears. This boron-nitride is often called white graphite because it has similar physical properties to graphite. It is also known as mica, silicates, silicate, silicate and fatty acid. These are commonly referred to collectively as white solid oils.
7. Boron-nitride may also be added to other materials. Boron-nitride fiber is made by boron nutride and has medium to high functionality. It can be used as an inorganic, synthetic engineering material in the chemical and textile industries, as well in other industrial areas.
