In this paper, correlation between CMZT melt state and structure properties of crystals, grown by vertical Bridgman method, was investigated. The Cd_0.9-xMn_xZn_0.1Te crystals with various Mn composition (x = 0.1; 0.2) were grown by two-step preparation method from high purity elemental components. We have conducted series of crystal growth runs with different melt superheating degree over the alloys melting temperature. As a result, we have got the ingots with various crystalline structures and properties. It was concluded that worth crystalline structure had the bulks which were grown from the melt with lowest superheating degree. We have determined also that band gap rose (from 1.67 at x=0.1 to 1.79 eV at x=0.2) with Mn content increasing.
