Silica Crucibles for Molten Germanium with a Boron Nitride-Containing Composite Inner Layer

  • Published:
Inorganic Materials Aims and scope

Abstract—

A process has been developed for the fabrication of double-layer silica ceramic crucibles with a composite inner layer containing 25 wt % boron nitride. We have studied the wettability of the container material by molten germanium in an argon atmosphere at a temperature of 1000°C. The contact angle has been determined to be 128°, exceeding that of BN-free silica ceramics by ~8°. The work of adhesion evaluated from the contact angle is 0.25 J/m2.
