Description

Sintering furnace

Technical Field

Background

Silicon carbide ceramic (SiC) is a novel material developed by modern technology, and has ultrahigh bending strength, excellent oxidation resistance, good corrosion resistance, ultrahigh abrasion resistance and ultralow friction coefficient at normal temperature, and ultrahigh strength and creep resistance at high temperature, so that the silicon carbide ceramic is the best composite material in the known ceramic materials. Particularly, in recent years, the toughness and strength of silicon carbide ceramic materials are further enhanced by the sequential appearance of SiC ceramic-based complex phase ceramics, such as fiber (or whisker) reinforcement, heterogeneous particle dispersion strengthening, gradient functional materials and the like.

Because the sintering temperature of the silicon carbide ceramic is higher, the sintering temperature is generally up to 1450-1750 ℃, and the phenomenon of volatilization of silicon steam exists in the sintering process, the silicon steam in the sintering process of the silicon carbide ceramic is easy to cause damage of a sintering chamber, and the sintering process of the silicon carbide ceramic is greatly influenced. In the prior art, in order to avoid the occurrence of the above situation, a layer of material which is not reacted with Si under normal conditions is sprayed on the furnace wall of the sintering furnace and the outer surface of the heating device, and then the material is dried at the temperature of about 300 ℃, so that the corrosion of silicon steam to the sintering furnace is avoided in this way. Although the corrosion of silicon vapor to the sintering furnace can be reduced to a certain extent by the mode, the furnace wall of the whole sintering furnace and the outer surface of the heating device need to be covered during spraying, the spraying area is very large, the workload is very large, and the production cost is extremely high.
