An inorganic reaction system comprising a lead-bismuth-tellurium composition of Formula (I): Pb a -Bi b -Te c -M d -O e , wherein 0 < a, b, c and d ¤ 1, a + b + c + d = 1, 0 ¤ d ¤ 0.5, a:b is between about 5:95 and about 95:5, a:c is between about 10:90 and about 90:10, b:c is between about 5:95 and about 95:5, (a+b):c is between about 10:90 and about 90:10, e is a number sufficient to balance the Pb, Bi, Te, and M components, and M is one or more additional elements. |
