Thorium monosilicide is a binary inorganic chemical compound of thorium and silicon with the chemical formula ThSi.[1] The compound is one of several known thorium silicides, and its properties and potential applications have been investigated.
Synthesis
ThSi was first observed in 1953 when samples of ThSi1.0 were heated in vacuum to 1700 °C, resulting in the formation of ThSi and β-ThSi2.[2]
Physical properties
Thorium monosilicide has a orthorhombic crystal structure with the space group Pbnm. The compound is isostructural with ZrSi and USi.[3][4]
