Opened boron carbide in 1893 by chemist Moissan, combining boron with carbon. This produces dark crystals. The binary compound began to be used in various fields of production.
In terms of hardness, the substance is not inferior to the hardest natural mineral, for which it received the name "black diamond". It has a wide range of chemical, physical and mechanical properties and is considered a quality abrasive.
Connection features
It has a complex crystal structure, due to which:
- does not oxidize (does not rust) in air;
- insoluble in water, acids, but boiling alkali will lead to its destruction.
B₄C is obtained by hot pressing in an electric furnace, where the temperature reaches 2450 ° C. The substance is discharged in powder form.
Products made from chemically resistant elements are characterized by high strength and hardness. Manufacturers offer boron carbide to buy in bulk with delivery to the destination.
Using grainy material
The synthesized substance is used for different purposes:
- When grinding and polishing metal, wood and other surfaces, the cutters after prolonged use become dull and spoil the product, and a tool that contains boron carbide comes to the rescue. Such a device will straighten and clean the sharp edges of the grains of the convexity of the surface and make it even.
- In the manufacture of laboratory glassware; in protective elements of individual protection of a person (in plates of body armor); pipes of sandblasting machines .
- In electronics and nuclear industry, boron carbide absorbs neutrons - slows down their action.
- A material based on carbide powder is required for ultrasonic processing, including crushing, for example, stone;
- Boron carbide paste is used when fine grinding is required;
- Lapping powder is required when creating boilers and steam generators - they are used to process steam-water fittings.
- Boron carbide is used for grinding stones in jewelry, spraying it under pressure, cleaning various surfaces.
- The method of borating during chemical-thermal treatment strengthens the outer side of metals and alloys - the surface of the structure becomes more resistant.
Boron carbide is sold by suppliers, the price per kg varies as depends on the brand of the product, i.e. on compliance with GOST, and on the degree of granularity of the substance. You can buy boron carbide from us https://www.umeks.ru/catalog/abrazivy /karbid-bora-gost-5744-85 /
