Crystals of Cu2ZnSnS4, Cu2ZnSnSe4 compounds and Cu2ZnSnS4х Se4(1-х) solid solutions have been grown by directional crystallization of the melt. The composition of the grown crystals was determined by X-ray microprobe analyses, XRD was used for determination of their structure. It was established, that both starting compounds Cu2ZnSnS4, Cu2ZnSnSe4 and Cu2ZnSnS4х Se4(1-х) solid solutions on their base are crystallized in tetragonal structure. Unit cell parameters a and c change linearly in accordance with Vegad’s law. State diagram was built using DTA method, which are characterized with small temperature interval of crystallization and it can be attributed to the firs type on Rozebom’s classification. Microhardness and density of the indicated crystals have been measured. It has been established, that microhardness changes with maxima on composition x , density - linearly. |
