The silicon reacts with the carbon forming more SiC which bonds the initial SiC particles. Sintered SiC is produced from pure SiC powder with non-oxide sintering aids. Conventional ceramic forming processes are used and the material is sintered in an inert atmosphere at temperatures up to 2000ºC or higher.
2013/1/1· We have performed a comparative study of nine predominant gas molecules (H 2, H 2 O, O 2, CO, CO 2, NO, NO 2, NH 3, and CH 3 OH) adsorption property on the top surface of the (10, 0) zigzag single-walled pristine Carbon nanotube (C-CNT), Boron doped carbon nanotube (B-CNT), and Silicon doped carbon nanotube (Si-CNT) are investigated by using density functional theory (DFT) …
2008/11/14· This paper reports on preliminary tests of the performance of boron-doped diamond powder (BDDP) as a stationary phase in electrochemically modulated liquid chromatography (EMLC). EMLC manipulates retention through changes in the potential applied (E(appl)) to a conductive packing.
The silicon did not diffuse into boron carbide grains to produce a solid solution of Si-doped boron carbide; instead the silicon reacted with impurities in the starting powder to form β-SiC and

Silica, as sand, is a principal ingredient of glass--a material with excellent mechanical, optical, thermal, and electrical properties. Ultra high purity silicon can be doped with boron, gallium, phosphorus, or arsenic to produce silicon for use in transistors, solar cells, rectifiers, and other solid-state devices which are used extensively in the electronics industry.

The depth of a heavily B doped Si layer was measured for different feature sizes, trench openings, and aspect wide trenches to 1.5 micrometers at the bottom of 2 micrometers wide trenches. The diffusion layer on the sides of the trenches for a 30 min B diffusion was 3.25 micrometer thick and it is independent of the trench opening and the trench aspect ratio.
2019/12/6· The structure and anode performance of Li‐ion batteries for three different forms of carbon materials (powder, spheres, fibers) and three boron‐doped samples have been studied comparatively. The characterization and properties were obtained by X‐ray diffraction, X‐ray photoelectron spectroscopy, Raman spectroscopy, and electrochemical measurements.
The purity of the boron powder at this stage is 85.9%-wt (M-B-86), comprising 10-12%-wt Mg, as well as small amounts of boron oxide and sub-oxides as further impurities. Further purifiion of the powder can be achieved by reduction of the Mg content.
Amorphous boron is a brown powder, though crystalline boron is black, hard (9.3 on Mohs'' scale), and a weak conductor at room temperature. Elemental boron is used as a dopant in the semiconductor industry, while boron compounds play important roles as light structural materials, nontoxic insecticides and preservatives, and reagents for chemical synthesis.
