The crystal is a hexagonal crystal, similar in structure to graphite. Because of its performance similarities, it is often called “white Graphite”.
Boron Nitride is an excellent dielectric at high temperatures. It is an excellent heat dissipation and high temperature insulating material. Boron Nitride is chemically stable, and it can resist erosion by most molten metallic materials. It also has self-lubricating characteristics.
Ceramics made from Boron Nitride are used in many industries and production.
Research on boron Nitride is currently focused primarily on the hexagonal (hBN) and cubic phases (cBN). Hexagonal Borosidria has good performance at high temperatures and is thermally conductive. Recent studies show that the hexagonal phase also exists in a thermodynamic equilibrium state at room pressure and temperature. It is still used in the production of cubic boron-nitride as a main raw material. Cubic Boron Nitride is a synthetic material with many application possibilities.
As a rule, hexagonal boron-nitride is used in the high temperature/high pressure method. The excellent properties of cubic boran nitride have attracted many scientists to research the synthesis of cubic boran nitride. The number of new preparation methods is endless, and they are all moving towards simple and feasible directions that are low-temperature and low-pressure. The synthesis of nano-boron nitride and its application in boron ceramics has been a hot topic for the past few years.
Hexagonal boran nitride has been called white graphite due to its similarity in crystal structure to graphite. In addition, it shares similar chemical and physical properties with graphite such as thermal conductivity, good lubricity. Hexagonal boran nitride can be used to make sintered ceramics. H-BN ceramics are used widely in a variety of fields, including high-temperature insulating components, atomic energy and metallurgy. The superior performance of cubic boron-nitride makes it a popular raw material in the synthesis.
Ceramics containing boron-nitride exhibit excellent thermal stability, as well as dielectric properties. It is among the few compounds which can reach a temperature of decomposition. It exhibits excellent thermal and electric stability over a wide temperature spectrum. This type of ceramic is not currently used in radomes due to its low strength, hardness and elasticity. It also has a high thermal conductivity, but it lacks corrosion resistance.
In the field of materials science, boron is nitride is a highly preferred advanced ceramic material due to its superior mechanical characteristics. Due to the harsh conditions in the current synthesis, this has an impact on boron nitride’s application to some extent. This new synthesis method has been a major focus in boron research. Select a reaction precursor with excellent thermodynamic properties and use them to reduce the temperature induced externally and the reaction temperature. This will allow you to control the product’s morphology better. Controlling the reaction process and particle size can be controlled by choosing the right reaction precursor and using its thermodynamic properties.
