Why does diamond have a higher melting point than …

You have asked “Why does diamond have a higher melting point than silica?”. Silica, also called quartz has a formula SiO2. Diamond is made of covalently bonded carbon atoms (C) and has no oxygen. The analog for silica in the carbon case is CO2 and

Why Diamond has higher melting point than Silicon …

Neither diamond nor silicon carbide melts at standard pressures. > However, they both sublimate at high temperatures. Structures Both diamond and silicon carbide have a tetrahedral covalent network structure. Diamond Silicon carbide Physical Properties Diamond does not melt at ordinary pressures. It converts to graphite and sublimates at about 3680 °C.
