How is silicon boride SiB6 powder produced?
Overview of Silicon Boride SiB6 Powders
Silicon boride (also known as borosilicide) is a lightweight ceramic compound composed of silicon and boron. Silicon boride or hexaborosilicide is a glossy black-grey powder. The chemical formula is SiB6. The molecular weight is 92.95. The relative density is 2.47 g/cm3 and the melting point is 2200℃. The hardness is between diamond and ruby. Silicon hexaboride can conduct electricity. It is insoluble in water. Surfaces are oxidized when heated in chlorine and water vapor.
How is silicon boride SiB6 powder produced?
A step of preparing silicon boride powder is as follows:
The silicon powder with an average particle size of less than 1 micron and the boron powder with an average particle size of less than 20 microns are mixed uniformly through a ceramic ball milling tank; the weight ratio of the silicon powder and the boron powder is 2.85-2.95:7.
After loading into the crucible, put it into a gas protection furnace, pass argon gas, heat up to 1400-160 ° C, and keep it for 50-70 minutes; when the insulation starts, put ASIC14 into the furnace, 3-5ml per minute, dripping time 9-11 minutes; after cooling, pulverize with a ceramic pot ball mill to obtain the final SiB6.
