Problems solved by technology

Graphite plate has good thermal conductivity, but it is easy to oxidize at high temperature, the accuracy cannot be guaranteed, and its service life is short. At the same time, it is easy to generate carbon monoxide, carbon dioxide and other gases in the sintering furnace, which is not conducive to sintering
[0004] The corundum-mullite setter plate is currently the most used ceramic setter plate, which has the advantage of not being easily oxidized. For example, the Chinese invention patent with the publication number CN102674864A discloses a corundum-mullite setter plate formula: it is made of electrofused Mollite Come stone, fused white corundum, tabular corundum, a-A1 2 o 3 It is composed of fine powder, kaolin, activator, and binder, but its thermal conductivity is poor, and the temperature difference between the upper and lower ceramic setters is large, which makes the performance of the product uneven.

Description

technical field [0001] The invention relates to a vitrified bond, a ceramic-metal composite material and a preparation method thereof, and a composite material setter plate, belonging to the technical field of superhard material product manufacturing. Background technique [0002] The sintering process of superhard materials is divided into hot-press sintering and cold-press sintering. Hot-press sintering is carried out at the same time as heating and pressure during sintering. Hot-press sintered products have less porosity, high density and stable performance, but the number of sintering at one time is small, Low production efficiency and high production cost. Cold-press sintering is free sintering under no pressure. Cold-press sintering products have the advantages of high porosity, good sharpness, large number of sintering at one time, low production cost, and are suitable for the production and processing of special-shaped products. They are more and more popular in prod...
