What's boron-nitride?

Boron Nitride is a heat resistant chemical refractory chemical of boron, nitrogen. Its chemical formula is: BN. Boron nitride material exists in many forms, such as carbon lattices that have a similar structure or other electrons.

Caracteristics of Boron Nitride

Boron Nitride is composed of both nitrogen and boron elements. It is possible to divide the crystal structure into cubic and hexagonal Boron Nitrides.

Hexagonal boron nutride's crystal structure is similar to graphite. The powder is light in weight and loosely lubricated. Additionally, its properties are similar to graphite, including high temperatures resistance and chemical stability. But, it has different properties than graphite. One example is that graphite conducts well while boron Nitride acts as an excellent insulation material.

 Cubic Boron Nitride has outstanding physical and chemical characteristics. This material is hardier than diamond. In addition, the high strength of cubic boron nitride makes it a great candidate for many applications. Cubic boron-nitride, which is also a semiconductor material at high temperatures with good properties and thermal conductivity makes it the most popular. The existing techniques for making them are not easily adaptable.

A synthetic method to make boron-nitride

Research on the synthesis boron nutride in recent years has mainly focused on low temperature, low pressure, nanometerization. On the basis of these traditional synthetic methods, numerous new synthetic methods have been created that offer great potential for development.

  1. Hydrothermal synthesis is the use of water in the hydrothermal reaction to dissolve insoluble or normally insoluble compounds. Recycling is possible for this hydrothermal synthesis process. Two characteristics of hydrothermal synthesizing are its low temperatures and closed containers. This environment helps to prevent the components becoming volatile. The hydrothermal method is low-temperature and low pressure synthesis that can be used to create cubic boron nutride at low temperatures.

  2. Technology that self-propagates: The application of external energy to stimulate high-exothermic chemical reacts. A local reaction happens in the system and forms the front (combustionwave), then the chemical reaction proceeds rapidly with support from its own heat release. This spreads the flame throughout the entire system. It is an old method of inorganic synthesizing, however it was only used for the recent synthesis of Boron Nitride.

  3. Carbothermal technology for synthesis of silicon carbide: Boric acid is used on the surface, while carbon acts as the reducing agent. Boron nitride can be obtained by reacting with ammonia. It is extremely pure. This preparation is very useful.

The good news is that there are many different ways of preparing boron nutride. As functional ceramic materials are continually improved, new methods for preparing boron nutride will continue to be developed. The new techniques have opened new avenues for application research in boron nutride ceramics.

Applications related to the boron Nitride

Boron Nitride is a good thermal conductor and can be used for high-frequency electronic insulation, heat sinks in integrated circuits and accessories to ion missiles. This type of object has complex shapes, and requires high processing precision. Boron nitride's excellent processing performance is able to meet these requirements. Additionally, boron Nitride has good pressure resistance, resistance and dielectric qualities, which can be used for ultra-high-voltage wire insulation materials.
