A new semiconducting material, a compound of aluminum and antimony, has been developed at the Battelle Memorial Institute in Columbus, Ohio. This potential competitor of germanium and silicon has already been used to make rectifiers with good high‐temperature characteristics, and possibly may also be used in making transistors. The cost of both aluminum and antimony is less than fifty cents per pound, compared with almost $350 per pound for germanium, and, although raw material cost is only a part of the expense involved in manufacturing a transistor or rectifier, the tremendous price difference makes the aluminum‐antimony compound a promising material for further study.
