I made a primitive cell consisting of 2 atoms and changed it to 2x2x2 super cell in ''edit -> edit data -> unit cell'' option. I expected I will get a super cell consisting of 16 atoms
Silicon carbide ceramics with little or no grain boundary impurities maintain their strength to very high temperatures, approaching 1600 C with no strength loss. Chemical purity, resistance to chemical attack at temperature, and strength retention at high temperatures has made this material very popular as wafer tray supports and paddles in semiconductor furnaces.

Wall flow monoliths are made of specialized ceramic materials such as cordierite and silicon carbide. is given for square cell geometry by Equation (1). The metric unit of cell density is 1/cm 2, but the US customary unit of cells per square inch (cpsi) remains
28/1/2009· In 2007, we found superconductivity in the stoichiometric composition of carbon and silicon: heavily boron-doped silicon carbide (SiC : B) . One interesting difference between these three superconducting systems is the well-known polytypism in SiC meaning that SiC exhibits various ground states of slightly different energy.

The unit cell in a certain lattice consists of a cube formed by an anion at each corner, an anion in the center, and a ion at the center of each face. The unit cell contains a net: A.3 anions and 4 ions B.5 anions and 3 ions C.2 anions and 3 ions D.2 anions
1/6/2015· Sintered silicon carbide ceramics typically are produced using submicrometer powders that have been extracted from an Acheson furnace and ground to a fine particle size. Boron and carbon are used as sintering aids to achieve improved densifiion during sintering which is typically conducted at a temperature on the order of 2500 °C.
