About Amorphous Boron B Powder:
Boron powder is a black or dark brown powder, which can react with fluorine at room temperature and will not be corroded by alkali and hydrofluoric acid aqueous solutions. Boron powder is also called amorphous boron. Boron has a high mass calorific value and volume calorific value. It is a light brown to gray-black powder with relatively active chemical properties, but it is relatively stable at room temperature and will be oxidized when the temperature reaches 300 degrees Celsius. The ignition level is very high, requiring 700 degrees Celsius to ignite. Boron powder can react with oxygen, nitrogen and sulfur, or it can directly combine with certain metals to form certain borides. We supply boron powder for sale.

Amorphous boron powder is a brown powder; amorphous boron is a brown powder. Amorphous boron is a brown powder. Crystalline boron is black, very hard (approximately 9.5 at Mohs hardness), and has a poor conductor at room temperature. Element boron is used as a dopant in the semiconductor industry, and boron compounds play an important role as light structural materials, pesticides and preservatives, and chemical synthesis reagents.

Properties of Amorphous Boron B Powder :
Elemental boron CAS 7440-42-8 is a black or dark brown powder, pure boron powder is 95%. When it is oxidized in the air, it will prevent the internal boron from continuing to oxidize due to the formation of a boron trioxide film. It can react with fluorine at normal temperature and is not corroded by hydrochloric acid and hydrofluoric acid aqueous solution. Boron is insoluble in water, powdered boron is soluble in boiling nitric acid and sulfuric acid, and most molten metals such as copper, iron, manganese, aluminum, and calcium.

How is Amorphous Boron B Powder produced?
There are two main techniques to obtain pure boron powder: via-gas and magnesiothermic reaction. The first technique uses hydrogen gas to reduce gaseous boron trichloride (BCl3), whereas the latter uses a combination of heat and magnesium to reduce the boron trioxide (B2O3) to elemental boron.
Applications of Amorphous Boron B Powder:
Boron powder is commonly used in metal smelting, electronic product manufacturing, ceramic manufacturing, chemical industry and nuclear industry, etc. The specific functions of boron nitride are as follows:
1. Boron powder can be used to make various boron-containing compounds, used as raw materials for the production of boron fibers, and important raw materials for the production of high-purity boron halide;
2. Boron powder is added in the form of a compound as a gas scavenger for the smelting of special alloy steel or molten steel;
3. Boron powder is used as high-energy fuel for rocket spacecraft,
4. Boron powder is used as the ignition pole of the ignition tube in the electronics industry;
5. Boron powder replaces precious or scarce metals;
6. Boron powder is used as a protective material for the atomic energy industry and the control rod in the atomic reactor;
7. Boron powder also can be used as a catalyst for organic chemical reactions.
Storage Condition of Amorphous Boron B powder :
Damp reunion will affect B powder dispersion performance and using effects, therefore, amorphous boron B powder should be sealed in vacuum packing and stored in cool and dry room, the amorphous boron B powder can not be exposure to air. In addition, the amorphous boron B powder should be avoided under stress.
