High Purity Silicon Boride SiB6 Powder CAS 12008-29-6, 99%

Hasad Foods, the agricultural investment arm of Qatar's sovereign wealth fund, said the government would increase its grain reserves from 250,000 tons to 300,000 tons in the near future, which is enough to feed the population for six months.  

With a lot of deserts, Qatar suffers from water shortages, and Qatar depends on food imports for a long time. Recently, the ongoing tension in Ukraine has caused global food supply tension and rising prices.

In addition to that, the geopolitical situation also affects the supply and prices of many commodities like the Silicon Boride.

About Silicon Boride SiB6 Powder:
Silicon boride (Silicon Hexaboride) is a shiny black-gray powder with a relative density of 3.0g/cm3 and a melting point of 2200°C. Silicon boride is a lightweight ceramic compound formed between silicon and boron. It is insoluble in water, resistant to oxidation, thermal shock, and chemical attack, especially with high strength and stability under thermal shock. The grinding efficiency is higher than that of boron carbide.
The SiB6 crystal structure includes interconnected icosahedrons (polyhedrons with 20 faces), icosahedral hexahedrons (polyhedrons with 26 faces), and isolated silicon and boron atoms. Compared to hexaboride, it is metastable. However, since crystal nucleation and growth are relatively easy, they can be prepared.
When heated in air or oxygen, the surface of SiB6 is oxidized, and it is attacked by boiling sulfuric acid and fluorine, chlorine and bromine at high temperatures. Silicon boride is conductive. The hexaboride has a low thermal expansion coefficient and a large nuclear cross-section for thermal neutrons. Feel free to send an inquiry to get the latest price if you would like to buy Silicon Boride SiB6 Powder in bulk.

Feature of Silicon Boride SiB6 Powder: 
1. Nano-silicon boride has high purity, small particle size distribution, high specific surface area.
2. The melting point up to 2230 °C. It can not be soluble in water and anti–oxidation and high resistance to chemical attack. especially in the high thermal impact and stability;
3. Grinding efficiency of silicon boride is higher than that of boron carbide, it can be used as abrasives, grinding and engineering ceramics such as nozzles, gas turbine blades and other different sintering conditions and sealing line

How is Silicon Boride SiB6 Powder produced?
A kind of step of preparing silicon boride powder is as follows:
Silicon powder with an average particle size of less than 1 micron and boron powder with an average particle size of fewer than 20 microns are mixed uniformly by a ceramic ball milling tank; the weight ratio of silicon powder and boron powder is 2.85-2.95:7.
After loading the crucible, put it into the gas protection furnace, pass in argon gas, and heat up to 1400-160 (TC, hold for 50-70 minutes;
At the beginning of heat preservation, put ASiCl4 into the furnace, 3-5ml per minute, dripping time 9-11 minutes;
After cooling, the final SiB6 powder product is obtained by crushing with a ceramic pot ball mill.

Application of Silicon Boride SiB6 Powder:
Main uses of silicon boride SiB6 Powder:
1. Used as various standard abrasives and grinding cemented carbides;
2. Used as engineering ceramic materials, as various standard abrasives, and grinding cemented carbide.
3. It is also used as engineering ceramic materials, sandblasting nozzles, and manufacturing blades of gas engines and other special-shaped sintered parts and seals.
4. Used as an anti-oxidant for refractory materials.

Storage Condition of Silicon Boride SiB6 Powder:
The damp reunion will affect SiB6 powder dispersion performance and using effects, therefore, silicon boride SiB6 powder should be sealed in vacuum packing and stored in cool and dry room, the silicon boride SiB6 powder can not be exposure to air. In addition, the SiB6 powder should be avoided under stress.

Packing & Shipping of Silicon Boride SiB6 Powder:
We have many different kinds of packing which depend on the silicon boride SiB6 powder quantity.
Silicon boride SiB6 powder packing:vacuum packing, 100g, 500g or 1kg/bag, 25kg/barrel, or as your request.
Silicon boride SiB6 powder shipping: could be shipped out by sea, by air, by express, as soon as possible once payment receipt.

Safety Statements 26-36
Transport Information N/A

Because of the conflict between Russia and Ukraine, there is a shortage of natural gas supply. At the same time, other renewable energy sources cannot produce enough electricity, so electricity prices have soared in many countries of the world. For this reason, I assume the supply and prices of the Silicon Boride would keep being influenced by the high energy prices.
