The melting point is the highest temperature at which crystallization may occur. It is also a temperature at which a solid (crystal) turns into a liquid. We say that such a body melts. The melting point is specific for a given substance. For example, the melting point of ice (frozen water) is 0 °C. The melting point depends on the pressure.

English Abstract The values of melting points of selected refractory oxides were critically assessed and the following recommended values are given (in°C): SiO 2 1726 ± 10; TiO 2 1892 ± 30; ZrO 2 2710 ± 25; Al 2 O 3 2054 ± 6; Sc 2 O 3 2485 ± 20; Y 2 O 3 2439 ± 12; MgO 2826 ± 30. No values for the melting points of BeO and CaO could be recommended.
