Diffusion crucible and slab member with common metal component in the vapor phase |
摘要 |
A slotted crucible for altering the nonstoichiometry of a crystalline member by promoting conditions of vapor phase equilibrium between the member and the slotted crucible in which it is placed. The slotted crucible comprises material sharing a common vapor species with the crystalline member and provides an atmosphere of substantially constant thermodynamic activity with respect to the shared vapor phase upon isothermal heating of the member and crucible.
