Abstract

The invention discloses a hot pressing sintering mold and a using method thereof. An inner mold sleeve of the hot pressing sintering mold is sleeved with an outer mold sleeve, a first through hole penetrating through the upper surface and the lower surface of the inner mold sleeve is formed in the inner mold sleeve, an upper pressing head is inserted into the upper end of the first through hole, a lower pressing rod is inserted into the lower end of the first through hole, and the lower end of the lower pressing rod is inserted into a lower pressing head; and two graphite flakes are arranged between the upper pressing head and the lower pressing rod, and a sintering sample is placed between the two graphite flakes. The hot pressing sintering mold is easy to disassemble and assemble before and after sintering, the sample and the mold are not damaged, the sample can be rapidly and conveniently prepared, and the service life of the mold is prolonged.

Description

【Technical field】 [0001] The invention belongs to the technical field of preparation of ceramic material sintering technology, and in particular relates to a hot-pressing sintering mold and a use method thereof. 【Background technique】 [0002] In the field of ceramic material research, many materials with excellent performance are prepared by powder sintering, but in the initial research and development process of the material, it is necessary to repeatedly prepare the same sample, which requires repeated disassembly and assembly of the mold and filling of powder raw materials, and under the same conditions Carry out hot pressing sintering. The two indenters of the mold currently used are both dynamic indenters, and the installation position is not easy to determine based on experience. When the pressure is applied during sintering, the sample moves with the movement of the indenter, the position cannot be accurately controlled, and it is difficult to disassemble the mold. ...
