Silicon carbide is a typical substance of polytypism.Besides the cubic β-SIC,among the 67 kinds of α-SiC polytypes already discovered only 24 have been thoroughlyanalysed.They belong to three different space groups:C6mc,R3m,and C3m,with 15kinds belonging to the space group R3m.The crystal ...
Originally, the SiC polytypes crystal structure is represented by the space group symbol. In order to distinguish the single crystal silicon carbide of the same space group, a simpler symbol can be used: the crystal form symbol is represented by numbers + letters. Among them, the number represe...

In the iron-3.25% silicon alloy the carbides take the form of lenticular disks precipitated on {100} planes of the ferrite matrix; the crystal structure of this carbide was not determined but it is neither epsilon nor cementite. The disks are displaced by grain boundary films of cementite ...
The Formation and Crystal Structure of Silicon Carbide The presence of cubic β-SiC has been identified by X-ray photographs when graphite and silicon are heated together at temperatures as low as 1 150°C, and... A Taylor,DS Laidler - 《British Journal of Applied Physics》 被引量: 61发表...
The random stacking of two-dimensional hexagonal layers (RHCP), a relatively unique structure with randomly spaced elements, is included in the close-packing construction. When this structure was initially seen in cobalt metal in 1942, it was believed to be in a transitional and undesirable energy...
The Crystal Structure of Boron Carbide Several crystals of boron carbide, grown from molten Cu, Pt, and Pd solutions using natural occurring as well as isotopically enriched boron, give essentially identical values for the lattice parameters. These parameters are consistent w... HK Clark,JL Hoard...
