Overview of Silicon Boride

Boron silicon (Silicon Hexaboride) is a glossy black-gray powder with a loved one thickness of 3.0 g/cm3, and a melting point of 2200 ° C. Silicon boride is a light-weight ceramic substance developed in between silicon and boron. It is insoluble in water and immune to oxidation, thermal shock, and chemical strikes, specifically with high stamina and security under thermal shock. The grinding performance is more than that of boron carbide.

The SiB6 crystal framework consists of interconnected icosahedrons (polyhedrons with 20 faces), icosahedral hexahedrons (polyhedrons with 26 faces), and separated silicon and boron atoms. Contrasted to hexaboride, it is metastable. Nonetheless, considering that crystal nucleation and development are reasonably very easy, they can be prepared.

When warmed in air or oxygen, the surface area of SiB6 is oxidized, and it is assaulted by steaming sulfuric acid and fluorine, chlorine and bromine at heats. Silicon boride is conductive. The hexaboride has a reduced thermal development coefficient and a big nuclear cross-section for thermal neutrons.

Features of Silicon Boride SiB6 Powder

Nano-silicon boride has high pureness, a little bit of dimension circulation, and a high detail area.

The melting point is about 2230 ° C. It can not be soluble in water, is anti-oxidation, and has high resistance to chemical strikes. Specifically in the high thermal influence and security.

The grinding performance of silicon boride is more than that of boron carbide; it can be utilized as abrasives, grinding and design porcelains such as nozzles, gas generator blades, and various other sintering problems, and securing line.

How is Silicon Boride SiB6 Powder produced?

One of the methods for preparing silicon boride powder is as follows:

First, we carefully mix silicon powder, with an average particle size under 1 micron, and boron powder, with an average particle size under 20 microns, using a ceramic ball milling tank to ensure uniformity. The weight ratio of silicon powder to boron powder is maintained between 2.85:7 and 2.95:7.

Next, after loading the mixture into the crucible, we place it in a gas-protection furnace. We then introduce argon gas and gradually heat the furnace to 1400-1600°C, holding this temperature for 50-70 minutes.

At the start of the heat preservation phase, we introduce ASiCl4 into the furnace at a rate of 3-5 ml per minute, continuing this process for 9-11 minutes.Finally, once the material has cooled, we obtain the final SiB6 powder product by crushing it using a ceramic pot ball mill.

5 FAQs of Silicon Boride

Q1

Is silicon hexaboride stable?

Answer: Silicon hexaboride has good thermal stability and corrosion resistance and is characterized by high hardness and melting point. It is more complicated than steel and can be used as a material for cutting tools. Its melting point is about 2230 degrees Celsius, so it can be used in high-temperature environments.

Q2

What are the main uses of silicon hexaboride?

Answer: Manufacture of high-temperature ceramics or machining tools; preparation of wear-resistant materials such as cutting tools, bearings, and coatings; used in the preparation of some electronic devices;

Q3

What are the methods of preparing silicon hexaboride?

Answer: Direct reaction method: pure silicon and pure boron are directly reacted at high temperatures to produce silicon hexaboride.

Chemical Vapour Deposition Method: By mixing the gases of silicon and silicon diboride at high temperatures to react to produce a silicon hexaboride film.

Q4

Is silicon hexaboride toxic?

Answer: In general, it is relatively stable and non-toxic. However, since silicon hexaboride may produce toxic gases during its preparation, appropriate safety precautions should be taken during operation, such as wearing protective glasses and gloves and ensuring good ventilation. Also, please avoid direct contact with its powder form to prevent accidental inhalation or bodily invasion.

Q5

Differences between silicon boride and glass?

Answer: Silicon boride is a ceramic material, while glass is an amorphous material. Also, silicon boride crystallizes in a different way to glass, and the crystal structure of silicon boride can be seen as a semi-metallic compound. In contrast, glass does not have a crystal structure.
