三碲化二锑是一种无机化合物，化学式为Sb₂Te₃。它是一种灰色晶体，但是熔点、密度和颜色可能取决于采用的晶型。

三碲化二锑可由金属锑与碲单质在500–900 °C直接化合制得：

2Sb(l) + 3Te(l) → Sb₂Te₃(l)

Antimony telluride is an inorganic compound with the chemical formula Sb₂Te₃. It is a grey, crystalline solid, although its melting point, density and colour may depend on the crystalline form it adopts.
