叶碲铋矿研究中存在问题分析

Some problems in the study of pilsenite

叶碲铋矿最初定名为wehrlite ,结构式为Bi2 +xTe3-x,后于 1 982年改名为 pilsenite ,结构式相应改为Bi4 Te3。楚碲铋矿 (BiTe)的成分介于原叶碲铋矿的成分范围之内。有些研究者仍用原成分确定叶碲铋矿或把楚碲铋矿当作叶碲铋矿 ,本文旨在提醒研究者注意 。

Wehrlite with formula Bi 2+x Te 3-x was first found in Hungary. The name was changed to pilsenite in 1982 with the formula being changed to Bi 4Te 3, and tsumoite was found within the compositional range of former wehrlite. Nevertheless, some researchers have still taken the composition of wehrlite as that of pilsenite or taken tsumoite as pilsenite. This paper aims at reminding the researchers not to use the incorrect names.
