Silicon Dioxide has a high melting point - varying depending on what the particular structure is (remeer that the structure given is only one of three possible structures), but around 1700 C. Very strong silicon-oxygen covalent bonds have to be broken throughout the structure before melting occurs.
Silicon carbide - Wikipedia
Because natural moissanite is extremely scarce, most silicon carbide is synthetic. Silicon carbide is used as an abrasive, as well as a semiconductor and diamond simulant of gem quality. The simplest process to manufacture silicon carbide is to coine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1,600 C (2,910 F) and 2,500 C (4,530 F).

Carbide | chemical compound | Britannica
Carbide, any of a class of chemical compounds in which carbon is coined with a metallic or semimetallic element. Calcium carbide is important chiefly as a source of acetylene and other chemicals, whereas the carbides of silicon, tungsten, and several other elements are valued for their physical hardness, strength, and resistance to chemical attack even at very high temperatures.
For example, the maximum operating temperature of Silicon Impregnated SiC (SISC/RBSIC) Bonded Silicon Carbide is 1375 C, the melting point of silicon. Production Silcarb manufactures its NBSIC in a very controlled electric furnace where temperatures are very accurately maintained and pressures are regulated through the cycle.
