Sintering Behavior of Ultrafine Silicon …

Abstract. The pressureless sintering of ultrafine SiC powder (average particle size: 0·01–0·12 µm) obtained by vapor phase reaction method was investigated with an emphasis on the effects of powder properties and sintering aids. The ultrafine SiC powder showed a remarkable densifiion in the presence of both carbon and boron as sintering aids, but the sintering aids …

Refractive Index, Dispersion, and …

The refractive index of each of the four common silicon carbide polytypes has been measured over the visible range. The data were analyzed in an attempt to relate the birefringence to the relative hexagonal character of the polytype. A general relationship exists, namely, that the birefringence increases with increasing hexagonal character of the polytype.

Digital images of, (a) silicon carbide powder, (b) exfoliated carbon fibers, (c) ball milled mixture of carbon fibers and silicon carbide powder. The main motive for exfoliating the chopped fiber tows prior to ball milling was to further reduce the length of the CFs at a faster rate than conventional methods, and also to aid in the uniform dispersion of CFs in SiC powder.

Pigment concentrates - BYK

For tinting: After the grinding and finalization, the pastes are used for the final fine adjustment of the color, i.e. for nuancing. In this case, only a small percentage of the pastes are used. The individual components of the pigment concentrates (especially the grinding resin) then have virtually no obvious influence on the quality of the coating that has been tinted.
