Abstract
The invention uses a furnace retort made of silicon carbide to create a sintering furnace having no cold areas during debinding while having low heat losses during sintering. This is achieved by varying the wall thickness of the retort and taking advantage of the large increase in thermal conductivity of silicon carbide at lower temperatures. The special properties of silicon carbide also allow rapid cooling by exposing the outside of the retort directly to a high flow of cooling air.
Claims8
A sintering furnace comprising of:
- a retort made of silicon carbide;
- electrical heating elements placed outside the said retort;
- thermal insulation surrounding the said heaters and retort, and
- a source of cooling air capable of directing cooling air into the space between the thermal insulation and the retort, said cooling air directly touching the retort, to achieve rapid cooling at the end of the sintering.
