Crucible liners are widely accepted as part of the coating process, and are considered to be an integral component for coating success. Lower power requirements Reduced crucible damage Our crucible liners are compatible with many manufacturer's evaporation sources. Benefits Crucible liners provide thermal isolation between the evaporant material and the water-cooled crucible.
Crucible liners reduce the thermal gradient across the evaporant material.
This increases the thermal stability within the melt, thereby increasing heating efficiency and reducing particle ejection and oscillations within the molten material. Using separate liners for each evaporant material can reduce contamination and provide extra protection against crucible damage. Liner Materials Crucible liners are available in various materials. Carbon graphite and glassy coated carbon graphite are two of the more common materials used. They are popular due to their low cost and favorable thermal properties.
