Abstract

The invention discloses a temperature control-material feeding coupled zone fritting furnace which comprises a material feeding mechanism, a temperature test system, a heating body, a programming controller, a heat shield, a water cooling jacket, a hydrogen gas inlet control system and a vacuum system. Materials are\ conveyed to a high-temperature space through the material feeding mechanism according to a set feeding system. The heating body controls the temperature of the high-temperature space according to the set temperature schedule under the control of the programming controller, thereby achieving the aim of temperature control-material feeding coupling. The hydrogen gas inlet control system and the vacuum system control the atmosphere in the sintering process. The fritting furnace provided by the invention is suitable for preparing a crystalline ceramic gradient material, and also can be used for preparing other classified gradient materials with large length-diameter ratios.

Description

technical field [0001] The invention relates to a sintering furnace in a temperature control-material feeding coupling area, which belongs to the field of sintering equipment. Background technique [0002] Since the laser output of transparent ceramic laser materials in 1995, it has developed rapidly. In recent years, there are reports of Nd:YAG transparent ceramic composite structure. This material is only different in the concentration of Nd ions in the YAG transparent ceramic material, so the sintering temperature is consistent. There is a big difference from the transparent ceramic gradient material proposed by the present invention. In the transparent ceramic gradient material proposed by the present invention, the concentration of doping ions and the composition of the matrix material are all changed. Because this change leads to a difference in the sintering temperature of the material, the preparation of this material is highly difficult and innovative. The prepara...
