    Description / Table of Contents: On the Influence of Chemical Transport on the Habit of CrystalsThe chemical transport of silicon with silicon tetrachloride as transporting agent leads to crystals with octahedral shape. On the other hand in the presence of adsorbable impurities the transported silicon crystallizes in the shape of long needles.Chemical transport reactions of tellurium are successful with iodine or sulphur. The presence of adsorbable transporting agents has considerable influence on the habit of crystals.
    Notes: Beim Chemischen Transport von Silicium mit Siliciumtetrachlorid als Transportmittel erhält man oktaedrische Kristalle. In Gegenwart von adsorbierbaren Verunreinigungen kristallisiert das transportierte Silicium dagegen in langen Kristallnadeln.Tellur ist mit Jod oder Schwefel chemisch transportierbar. Die Anwesenheit des adsorbierbaren Transportmittels zeigt einen erheblichen Einfluß auf den Kristallhabitus.
