Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] Such as figure 1 The shown sapphire single growth furnace heat preservation device for convenient adjustment of temperature gradient includes an upper heat shield, a side temperature control system, and a lower heat preservation system. The side walls of the side temperature control system are set with different thicknesses in the height direction to adjust Temperature gradient in the growth furnace.

[0029] The side temperature control system includes a tungsten barrel 11, a heat preservation barrel 12, a temperature adjustment barrel 13, and a fastening barrel 14, and the tungsten barrel 11, the heat preservation barrel 12, the temperature adjustment barrel 13, and the fastening barrel 14 are sequentially integrated from the inside to the outside. The side temperature control system also includes a thermal insulation cover plate 15,...

Abstract

The invention relates to a sapphire single growth furnace heat preservation device capable of conveniently regulating temperature gradient. The device comprises an upper heat screen, a lateral temperature control system and a lower heat preservation system, wherein the side walls of the lateral temperature control system have different thicknesses in the height direction; and the lateral temperature control system is used for adjusting the temperature gradient in the sapphire single growth furnace. According to the device disclosed by the invention, the heat preservation system can be easily and moderately adjusted by virtue of the quality of crystals produced by each furnace turn, so that the temperature gradient suitable for large-size high-quality sapphire single crystal growth is formed, and the quality of the large-size crystals is improved; the heat preservation structure is diversified in functions, high in flexibility and adjustable, and the energy consumption can be greatly reduced; and meanwhile, the problems that the traditional tungsten-molybdenum heat preservation structure deforms in a high-temperature environment and is short in service life and high in cost and the like can be solved.

Description

technical field [0001] The invention relates to the technical field of sapphire single crystal growth, and more specifically relates to a sapphire single growth furnace heat preservation device for conveniently adjusting the temperature gradient. Background technique [0002] The hardness of sapphire reaches Mohs 9, which is second only to diamonds, and it has strong impact resistance and comprehensive scratch resistance; the sapphire mobile phone screen has high optical transmittance, small scattering, and can present more realistic colors and clear and bright mirror effects ; and extremely high sensitivity, which is more sensitive and precise than other protective films on the market, and the screen is smoother; the radiation resistance of sapphire is twice that of ordinary glass, which effectively reduces the radiation hazard of electromagnetic radiation to the human body. With the above characteristics, sapphire will be applied to related fields of smartphones (mobile ph...
