A New Quick Test to Determine the Structure of Opacified Glasses

The structure of glass opacified with phosphor is investigated as a function of its thermal prehistory using the positron annihilation method, x-ray phase, and electron microscope analysis. Structural differences are identified, which depend on the wall thickness of articles and the temperature conditions of annealing. It is proposed to use this method for a quick test of the homogeneity and the degree of annealing of opaque glasses.
