Методом микрорентгеноспектрального анализа определен состав полученных кристаллов, рентгеновским методом - их структура. Установлено, что как исходные соединения Cu2ZnSnS4, Cu2ZnSnSe4, так и твердые растворы на их основе кристаллизуются в тетрагональной структуре. Параметры элементарной ячейки а и с изменяются линейно в соответствии с законом Вегарда. Методом ДТА построена диаграмма состояния системы Cu2ZnSnS4 - Cu2ZnSnSe4, которая характеризуется небольшим интервалом кристаллизации, и ее можно отнести к первому типу по классификации Розебома. Измерена микротвердость и плотность указанных кристаллов. Установлено, что микротвердость с составом х изменятся с максимумом, плотность - линейно.</p></abstract><trans-abstract xml:lang="en"><p>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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кристаллы</kwd><kwd>структура</kwd><kwd>параметры элементарной ячейки</kwd><kwd>плотность</kwd><kwd>микротвердость</kwd><kwd>диаграмма состояния</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Todorov T.K., Tang J., Bag S. et al. // Adv.
