Abstract

The invention discloses a production device of a high-strength material silicon carbide ceramic. The production device mainly comprises a vacuum pump (J101), a buffer tank (F101) and a combustion furnace (B101). The vacuum pump (J101) is connected to the buffer tank (F101) and the buffer tank (F101) is connected to the combustion furnace (B101). The water inlet of the vacuum pump (J101) has the diameter of 170 to 180 mm.

Description

technical field [0001] The invention relates to a compound synthesis device, in particular to a production device of high-strength material silicon carbide ceramics. Background technique [0002] Silicon carbide ceramics, a high-strength material, are mainly used in nozzles, bearings, turbocharger rotors, static and moving blades of gas turbines, heat exchangers, etc. in the industrial sector. Not only has excellent room temperature mechanical properties, high bending strength, excellent oxidation resistance, good corrosion resistance, high wear resistance and low friction coefficient, but also high temperature mechanical properties are the best among known ceramic materials. The high temperature strength of hot pressing sintering, pressureless sintering and hot isostatic pressing sintering can be maintained up to 1600°C, which is the best high temperature strength material among ceramic materials, and the oxidation resistance is also the best among all non-oxide ceramics ....
