Boron powder(B powder) is a black or dark brown powder that reacts with fluorine at room temperature and is not corroded by alkali and aqueous hydrofluoric acid solutions. Boron powder is also called amorphous boron. Boron has a high calorific value of mass and volume. It is a light brown to grayish-black powder with active chemical properties, but is relatively stable at room temperature and oxidized when the temperature reaches 300℃. The ignition height is very high, it needs 700 degrees Celsius to ignite. Boron powder can react WITH OXYGEN, nitrogen, sulfur, or directly combine with some metals to form some borides.
Amorphous boron is a brown-black powder. Crystalline boron is black, very hard (Mohs hardness ~ 9.5) and a poor conductor at room temperature. Boron element is used as a dopant in the semiconductor industry. Boron compounds play an important role in light structural materials, pesticides and preservatives, chemical synthesis reagents and so on.

Properties of amorphous boron powder: Amorphous elemental boron is chemically more reactive than crystalline elemental boron. Crystalline boron is so hard that it is often used in place of diamond to make cutting tools or drill bits. In the process of metal smelting, a small amount of boron is added, on the one hand, as a deoxidizer, to prevent metal oxidation at high temperature; On the other hand, alloys are formed to improve the properties of metals. The element boron CAS 7440-42-8 is a black or dark brown powder. When it oxidizes in the air, it stops the internal boron from oxidizing further, resulting in a boron trioxide film. It reacts with fluorine at room temperature and is not corroded by hydrochloric acid and hydrofluoric acid aqueous solution. Boron is insoluble in water, and boron powder is soluble in boiling nitric and sulfuric acids, as well as most molten metals such as copper, iron, manganese, aluminum, and calcium.
Application of amorphous boron powder Amorphous boron powder is a kind of important energy material, in a composite solid propellant as a solid fuel, the calorific value of the boron is twice as tall as carbon above, is about 2 times of aluminum, magnesium, more than 2 times, its volume is almost three times the hydrocarbon fuel heating value, density is only slightly lower than aluminum, with the highest volume calorific value, in terms of its energy, b should be the best fuel, not of metal. The ignition temperature of amorphous boron is greatly reduced due to its irregular shape and large specific surface area. Amorphous BORON POWDER IS mainly used IN HIGH energy solid fuel, boron-containing FUNCTIONAL ceramics, space technology, explosive catalyst, airbag detonator, superconducting, borane, a variety of borides and high purity boron halide raw materials, metallurgy, glass, electronics and other industries.
