Claims20
A retort configuration having reduced contamination, comprising:
- a retort disposed within a furnace and configured to receive a inflow of process gas through a inlet;
- and
- at least one getter configured to lessen the number of reactive species within the retort during a thermal processing cycle.
A method of reducing contamination of parts during a thermal processing cycle, comprising:
- disposing a retort containing a part to be processed and at least one getter within a furnace;
- and
- providing a flow of process gas through the retort while conducting a thermal processing cycle, wherein the getter reacts with reactive agents in the furnace.
