OSA | Direct Analysis of Silicon Carbide Powder by Total …
Three silicon carbide powders having different grain size distributions were analyzed by total reflection X-ray fluorescence (TXRF) spectrometry with the appliion of slurry sampling. For the elements investigated (Fe, Ti, V, Cu, Ni, and Ca) the line-to-background ratios show a maximum value at a surface concentration of 12.5 mu g/mm2. For the realization of this surface concentration, a 25

Methods: Agarose powder, regular evaporated milk, Dulbecco''s phosphate-buffered saline (DPBS), n-propanol, and silicon carbide powder were homogeneously mixed with low temperature sensitive liposomes (LTSLs) loaded with a self-quenched near-infrared
Chopped silicon carbide with an initial length of 5 mm and diameter of 10-15 pm (Nicalon, Nippon Carbon Co. Ltd., Japan) were coined with the alumina to yield mixtures of 0, 10, 20, and 30 vol % fiber. The powder and fiber were milled dry to form a
alyst Butene-1,4-Diol by Silicon Carbide Supported Platinum …
The alytic properties of silicon carbide supported platinum alysts were tested in the hydrogenation of 2-butyne-1,4-diol (BYD) in aqueous phase. Before the reaction testing, the alysts were activated at 300 C for 2 h under the atmosphere of pure H2 with flow rate of 30 sccm. with flow rate of 30 sccm.
Efficient Preparation of Si3N4 by Microwave Treatment of …
In this study, the waste silicon powder generated in the production of solar-grade polysilicon scrap was used as the raw material, and silicon nitride (Si3N4) was directly efficient prepared by the microwave heating nitridation. The temperature raising characteristics of silicon powder by microwave heating and the influencing factors of the nitridation reaction process were studied. The

Tribochemical Polishing | Annual Review of Materials …
Tribochemical polishing, a novel polishing technique, is based on the dissolution of material, stimulated by simultaneous friction at contacting asperities. It uses hard polishing pads (cast iron, stainless steel, ceramic) and a polishing solution free of abrasive particles. Tribochemical polishing of ceramics (SiN, SiC) and tungsten has been demonstrated. Surface roughnesses less than 1 nm
