Graphite Sagger for Sintering Furnace
Graphite saggers are high temperature crucibles used to hold and protect ceramic, powder metallurgy, and electronic materials during sintering processes. Made from high density isostatic graphite, they withstand extreme temperatures and thermal cycling without deformation.
Our graphite saggers are precision machined to customer specifications, available in various shapes including rectangular, round, and custom geometries for different furnace sizes and loading requirements.
