Abstract

A method of manufacturing a semi-conductor material of stoichiometric composition XZ, where X consists of zinc or cadmium and Z consists of one or more of the elements sulphur selenium or tellurium, comprises heating at 200 DEG -400 DEG C. an intimate mixture of the finely powdered elements in the required proportions, in contact with water, sodium hydroxide or another aqueous liquid in a sealed vessel for from 18 hours to 5 days. The pressure developed within the vessel may be in the range 80 atm. to 500 atm. The initial powder mixture consists of particles sufficiently small to pass through a 300 mesh sieve (B.S.S.). Minor proportions of other elements can be included in the initial powder mixture and hence in the product XZ, for influencing the semi-conducting or other properties thereof.
