Stress Corrosion of Ceramic Materials.

Abstract

The critical fracture energy and susceptibility to environmentally enhanced fracture were shown to depend on the bonding in single crystals. Fracture energy results agreed with predictions based on force laws. Additions of lithium to basic solutions reduced crack growth rates in silica by over an order of magnitude. KIC and subcritical crack growth in capacitor ceramics were in a function of composition and microstructure. Correlations between strength and dielectric aging rate were obtained for aplphia Z5U capacitor material.
