Reaction of solid SiO with calcium in various ratios at 900°C results in the formation of a mixture of CaO, CaSi and Ca₅Si₃. When the reaction (in a 1:3 ratio) is carried out at 750°C, CaO and Ca₃SiO are formed. The structure of the latter compound, which is erroneously described in the literature as "cubic Ca₂Si", was determined from powder diffraction data. In the reaction mixtures of solid SiO with strontium or titanium, SrSi, SrSi₂ and Ti₅Si₃ were identified. Reaction with aluminium did not result in the formation of a silicide, but of elemental silicon instead.
