Mar 15, 2012The silicon lump is levitated, melted and superheated by 200 K, then cooled by a helium flow and by varying the electromagnetic power. Three undercooling temperature measurements are done on the same undoped silicon droplet, the temperature of which is measured with a two-color pyrometer on the equatorial plane. Silicon carbide precipitates

Jan 01, 1991The alpha-silicon carbide was in the form of a material 10 grit and finer (75% 70-mesh or larger). The silicon furnace was started with an alpha-silicon carbide-containing charge which was a mixture of (a) lump Mt. Rose quartz, (b) briquettes which consisted of a mixture of coal, alpha-silicon carbide, and sand and (c) wood chips.

Mar 01, 2010The silicon carbide particles are nucleated within the melt only up to the stage at which the dissolution of boron carbide in the molten silicon raises the concentration of boron to its solubility limit. At this point, the ternary B 12 (B,C,Si) 3 compound starts to precipitate at the carbide/melt interface and forms the rim regions. Further

May 27, 1986Although these materials have attracted a great deal of attention, silicon carbide ceramics are thus far industrially available only in the form of powder or lump. When in the form of a whisker or whiskery crystal--a single unit crystal--silicon carbide exhibits much higher mechanical strength than lump crystals of the same material.
