Semiconducting glasses and the method of preparation thereof

摘要

Chemically stable, semiconducting glasses having a resistivity of from about 2 × 10.sup.7 to about 6 × 10.sup.8 ohm.sup.. cm contain 25 to 35 weight percent of vanadium pentoxide, 10 to 20 weight percent phosphorous pentoxide, and from 35 to 45 weight percent of molybdenum trioxide. These semiconducting glasses are melted readily, are castable into desired shapes, and offer good resistance to devitrification.
