Tīmeklismelting point, temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. More heat then will convert the solid into a liquid with no temperature change. When all the solid has melted, additional heat will raise the … Tīmeklis1978. gada 1. okt. · Single crystal LaB 6, EuB 6, CeB 6, BaB 6, (La, Eu)B 6, (La, Y)B 6, (La, Ba)B 6, (La, Cs)B 6, (Eu, Y)B 6 and (Eu, Ba)B 6, hexaborides have been grown from an aluminium flux using oxide powders.Crystals of ~1 mm or more per side have been synthesized.
