Description of Amorphous Boron Powder
Elemental boron CAS 7440-42-8 is a black or dark brown powder. 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 at normal temperature Amorphous Boron Powder is insoluble in water, powdered boron is soluble in boiling and most molten metals such as copper, iron, manganese, aluminum, and calcium.
There are two main techniques to obtain pure amorphous boron powder: via-gas and magnesiothermic reaction. The first technique reduce gaseous whereas the latter uses a combination of heat and magnesium to reduce the boron trioxide (B2O3) to elemental boron.

Application of Amorphous Boron Powder
Amorphous 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. Amorphous 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. Amorphous 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. Amorphous boron powder is used as high-energy fuel for rocket spacecraft,
4. Amorphous boron powder is used as the ignition pole of the ignition tube in the electronics industry;
5. Amorphous boron powder replaces precious or scarce metals;
6. Amorphous boron powder is used as a protective material for the atomic energy industry and the control rod in the atomic reactor;
7.Amorphous boron powder also can be used as a catalyst for organic chemical reactions.
