Tellurium
碲
Tellurium is a semiconductor with electrical conductivity about two orders of magnitude lower than the metals. Its chemistry is similar to that of sulfur, except that it is more metallic in character.
碲是一种半导体，其电导率比金属低两个数量级。它的化学性质与硫相似，但更具有金属特性。
Tellurium is found in the mineral nagyagite, a sulfide, along with lead, iron, antimony, and gold. Tellurium combines with gold to form krennerite and calaverite, both with the empirical formula AuTe2. These two minerals are said to be dimorphs of each other. Silver bonds to tellurium in the mineral hessite, Ag2Te. Gold and silver combine with tellurium to form the mineral sylvanite, AgAuTe4.
碲存在于矿物 nagyagite 中，这是一种硫化物，还含有铅、铁、锑和金。碲与金结合形成 krennerite 和 calaverite，这两种矿物的实式均为 AuTe₂。这两种矿物被认为互为同质多形体。银与碲在矿物 hessite 中结合，形成 Ag₂Te。金和银与碲结合形成矿物 sylvanite，其式为 AgAuTe₄。
