Description

technical field [0001] The present application relates to the technical field of high-temperature processing, in particular to a high-temperature sintering furnace. Background technique [0002] The sintering furnace is a kind of ceramic green body solid particles bonded to each other at high temperature, the grains grow, the voids (pores) and grain boundaries gradually decrease, and the total volume shrinks and the density increases through the transfer of substances, and finally becomes A furnace with a dense polycrystalline sintered body with a certain microstructure. Sintering furnaces mainly include vacuum hot pressing sintering furnaces and discharge plasma sintering furnaces. Among them, the vacuum hot-press sintering furnace is a sintering furnace that combines vacuum, hot-press forming and high-temperature sintering, and is widely used in the sintering of ceramic powder, ceramic ferrules and other zirconia ceramics. [0003] Put the raw materials that need high-te...
