About Boron Amorphous Boron:
The powder of Boron is black or dark brown in color. It can react at room temperatures with fluorine, and it will not corrode when exposed to alkali or hydrofluoric solutions.
Boron is also known as amorphous ore. Boron has high volume and mass calorific values. The powder is light brown or gray-black with relatively active chemical characteristics. It is stable when kept at room temperature, but will oxidize once the temperature reaches around 300 degrees Celsius. The ignition level of this powder is high. It requires 700 degrees Celsius in order to ignite. Boron can react with sulfur, oxygen and nitrogen. It can also combine directly with metals to create certain borides.

The brown powder is Amorphous Boron. Amorphous boron comes in a powdery brown color. Crystalline Boron is a dark black powder. It's very hard, about 9.5 Mohs. And it has poor conductivity. Elements boron are used in semiconductors as dopants, while boron compounds have important roles as structural materials, pesticides or preservatives and chemical synthesis agents.

Pure Boron Powder Properties:
Elemental Boron CAS 7440-42-2 is a powdery dark brown color. The boron will not continue to oxidize when the boron is exposed to air. This is because a film of boron trioxide forms. Hydrofluoric or hydrochloric aqueous solutions do not cause it to corrode. Boron is not soluble with water. However, powdered boran is soluble with boiling sulfuric acid and nitric, as well as most metals like copper, iron and manganese.

How do you produce Boron powder amorphous Boron?
The two main ways to get pure boron are via-gas or magnesiothermic reactions. The first technique reduces gaseous boran trichloride using hydrogen gas, while the second uses heat and magnesia to reduce boron dioxide (B2O3) into elemental boron.

Boron Powder Uses:
Boron powder has many applications in the metal smelting industry, ceramic manufacturing industry, chemical industry, and nuclear industry. Boron nitride has the following specific functions:
1. Boron powders can be used for a variety of boron compounds. They are also important raw materials in the production of high purity boron halide.
2. The compound of Boron Powder is used as a gas absorber in the smelting process of Special Alloy Steel or Molten Steel;
3. Boron powder is used in rocket fuel to provide high energy.
4. The electronic industry uses a powdered form of Boron as the ignition electrode for the ignition tubes;
5. Boron Powder replaces precious and scarce metals
6. Boron is used in atomic energy as a control rod and for protection.
7.Boron can be used to catalyze organic chemical reactions.

Storage condition of Boron Powder Amorphous Boron Powder:
The boron dispersion and use effects will be affected by damp reunion. Therefore, amorphous powder must be packed in vacuum and kept in a dry and cool room. Amorphous boron is also not to be used under pressure.

Packing & Shipping Boron Amorphous Powder :
The amount of amorphous boran powder determines the type of packing we use.
Amorphous boron Powder Packing: vacuum packaging, 100g,500g or 1kg/bag or 25kg/barrel or as per your request.
Shipping Amorphous Boron powder: it can be sent by air, sea or express as quickly as possible after receipt of payment.
