The Growth of Zinc Sulphide Single Crystals from Flux

Abstract

For the purpose of obtaining ZnS single crystals the growth from several inorganic salts was examined. Among these salts KCl was most adequate. Using this as flux needle-like crystals as large as 1 mm in diameter and 10 mm in length were obtained as well as thin flat crystals of about 4 mm in diameter. Most crystals were of wurtzite structure. In needle-like crystals c-axis was parallel to the needle-axis and in flat crystals it was vertical to the flat surface. The content of potassium in these crystals was determined to lie between 0.1 to 0.4 atomic percent.
