High melting point scandium
WebDescribed are precursor compounds and methods for atomic layer deposition of films containing scandium(III) oxide or scandium(III) sulfide. Such films may be utilized as dielectric layers in semiconductor manufacturing processes, particular for depositing dielectric films and the use of such films in various electronic devices. WebMelting point Calcium's melting point is variously quoted as 839°C or 842°C. All of the transition metals following it in the Periodic Table have higher melting points (apart from zinc, which doesn't count as a transition metal).

It develops a slightly yellowish or pinkish cast when oxidized by air. It is susceptible to weathering and dissolves slowly in most dilute acids. It does not react with a 1:1 mixture of nitric acid (HNO3) and 48.0% hydrofluoric acid (HF), possibly due to the formation of an impermeable passive layer. Scandium turnings ignite in the air with a brilliant yellow flame to form scandium oxide.
