SiC & Si3N4 Sinter Furnace

Description
Horizontal Sinter furnace is mainly used for reaction sintering, low pressure sintering, re-crystal sintering, HIP sintering of Sic ceramic product and it can also applied for sintering of Si3N4a and other ceramic parts.

Technical Features
1. The furnace uses electrical resistance heating with temperature compensation or multiple temperature zone control, assuring great temperature uniformity.
2. Unique ACME super high temperature and high current feeding technology achieves the equipment can be long term stable used at 2400°C.
3. Unique special designed high temperature infrared measurement technology is adopted with precision temperature control and close error.
4. Installed with special sealing muffle to minimize the silicon vapor and by-pass materials contamination to the heating element and heat insulation material.
5. The furnace uses special exhaust gas treatment device, which is friendly to environment and convenient for cleaning.
6. Horizontal vacuum sintering furnace has debinding system to complete debinding and sintering process in one furnace at one time.
