This to prepare cathodic evaporation of the targets of large dimensions and homogenous in the composition of mercury, cadmium telluride

摘要

P to the to prepare cathodic evaporation and mercury, cadmium telluride hydroxyacetals corresponding to the general formula cdhgte in which x is of the values lying in the range of about 0,14 has 0,60. / p & & p & is prepare of cadmium telluride and of mercury in the state of division, namely in the state of particles which have all the dimensions lower has 150microns, there is a mixture of the particles of mercury, cadmium telluride and finely divided up a / 00307 substantially uniform size of particles is introduced a quantity of particles mixed in a matrix to the desired dimensions, it is applied to these particles, a pressure sufficient to place the mercury, cadmium telluride and finely divided in the state of the object, compact and coherent having a density of at least 97 of the density theoretical, it releases the pressure and is removed from the object to be compact, to the desired dimensions, of the matrix, the quantity of particles mixed introduced into the mold being sufficient to achieve this object is a compact to the desired dimensions. / p & & p & the process according to the invention makes it possible for the first time of the to prepare vaporization of the targets of large dimensions. / p
