Novel Uses of Gravimetry in the Processing of Crystalline Ceramics
The recording microbalance has been utilized in studying a vapor phase reaction that occurs between two incongruently vaporizing ceramics at high temperature. The degree of nonstoichiometry and a model for solid state diffusion are established directly. Applications of the process are illustrated by determining crystal composition, by forming reproducibly tailored optical waveguides, and by reducing significantly the susceptibility to laser damage of LiNbO3 single crystals.
