Boron powder comes in two forms: solid black and silver-gray. Black crystal boron has the second hardest hardness of diamond and a more fragile texture.

Particle Size: 0.8-5um

Boron Powder Amorphous Boron Pulver:

Boron dust is either a black-colored or dark-colored powder. This powder can be used to react with fluorine at normal room temperatures and won’t be affected by acidic and alkali aqueous solutions.

Boron powder also known as Amorphous Boron Powder. Boron is high in both mass and volume calorific values. The powder is medium brown to grey-black and has active chemical properties. Although it can be stored at room temperature, the material will begin to oxidize once temperatures reach 300 degrees Celsius. To ignite, the ignition temperature is high at 700 degrees Celsius. Boron powder is able to react with nitrogen, oxygen and sulfur. Or, it can be mixed directly with certain metals in order to make certain borides.

Amorphousboron , which is a dark brown powder. While amorphousboron has a darker color, it is still a powder. Amorphous boron can be described as a brown powder. Crystalline Boron is a black powder that’s very hard, approximately 9.5 at Mohs Hardness. It has a low conductivity at ambient temperature. In the semiconductor industry element boron serves as a Dopant. Additionally, boron compounds are important as light structural materials and pesticides as well as chemical synthesis reagents.

Pure Boron Powder Properties:

A black or dark brown powder of elemental boron, CAS 7440-22-4-8. The boron trioxide films form when the internal boron is not oxidized by oxygen. Fluorine can react at normal temperatures and it isn’t corroded with hydrochloric and hydrofluoric acid. Although boron is insoluble when it is mixed with water, powdered Boron can be dissolved in boiling nitric and sulfuric acids, as well as most molten metallics, such as iron, copper, manganese and calcium.

What is Boron Powder Amorphous Boron powder made of?

You can obtain pure boron powder using two methods: via gas and magnesiothermic. To reduce gaseous sodium borontrichloride (BCl3) the first method uses hydrogen gas, while the second technique employs heat and magnesiothermic reaction to convert boron trioxide to elemental boron (B2O3).

Boron Powder Uses:

Boron powder is used extensively in electronic product production, metal smelting, and ceramic manufacturing. Here are some of the functions that boron Nitride performs:

1. Boron powder can then be used to create boron-containing compound, which are used as raw materials in the production boron fibres.

2. As a gas-scavenger to the smelting special alloy steel and molten steel, Boron powder may be used.

3. Boron powder is used in rocket fuels to power high-energy spacecraft.

4. The ignition pole in an electronic tube is made from Boron powder.

5. Boron powder is a replacement for precious or rare metals

6. Boron powder can be used to protect the atomic energy sector and control rods in an atomic reactor.

7.Boron powder is also a good catalyst for organic chemical reaction.

Boron Powder Amorphous Boron Powder Storage –

Amorphous Boron powder will suffer from dampening, which can affect its dispersion performance. Additionally, amorphous Boron powder should not be exposed to stress.

Packing & Shipping Boron Powder Amorphous Boron Pulp :

There are many options for packing, which depend on the amount of amorphousboron powder.

Packaging of Amorphous Boron Powder: Vacuum packaging, 100g to 500g or 1kg/bag at 25kg/barrel. Or as you request.

Shipping Amorphous Boron Powder: This could be done by ship, express or air once the payment has been received.
