Abstract HgTe crystal materials have a wide application prospect in the field of large array infrared detector due to its excellent photoelectric properties. In order to obtain HgTe single crystal with excellent temperature gradient performance, a new improved structure of thermal field in mercury telluride single crystal furnace is proposed. Through numerical simulation of the heat field in the furnace, the temperature distribution and the corresponding temperature gradient and heat flux density distribution in the furnace at different growth stages of the crystal are obtained. The temperature gradient in the furnace is about 4.88 ℃/cm;a five-zone heating test platform is set up,and the temperature gradient in the gradient zone is about 4.96 ℃/cm.
