Silicide

A silicide is a type of <a href="/facts/Chemical_compound/37FXqqtv">chemical compound</a> that combines <a href="/facts/Silicon/cgWx0hdr">silicon</a> and a usually more <a href="/facts/Electropositive/H7Vq7Uah">electropositive</a> element.
Silicon is more <a href="/facts/Electronegativity/H7Vq7Uah">electropositive</a> than <a href="/facts/Carbon/ukrgQexo">carbon</a>. In terms of their physical properties, silicides are structurally closer to <a href="/facts/Boride/Cf1ephFt">borides</a> than to <a href="/facts/Carbide/xfCMTjYJ">carbides</a>. Because of size differences however silicides are not isostructural with borides and carbides.
Bonds in silicides range from <a href="/facts/Electrical_conductivity/akyCKvMy">conductive</a> metal-like structures to <a href="/facts/Covalent_bond/EzMLf3Pz">covalent</a> or <a href="/facts/Ionic_bond/R6nUJI5u">ionic</a>. Silicides of all non-<a href="/facts/Transition_metal/0slGWoLQ">transition metals</a> have been described except <a href="/facts/Beryllium/dv295voP">beryllium</a>. Silicides are used in <a href="/facts/Interconnect/3BMeTFXp">interconnects</a>.
