What is Machinable Glass Ceramics ?

11-12-2020

Machinable Glass Ceramics are two-phase materials constituted by nanocrystals embedded in a glass matrix, and the volume fractions of crystalline and amorphous phases govern their properties.

 MGC

MGC Ceramic consisting of various oxide crystals in a matrix of siliceous residual glass offer properties not available with more common silicate crystals. In particular, glass-ceramics based on spinels and perovskites can be quite refractory and can yield useful optical, mechanical, and electrical properties. Possible applications for spinel glass-ceramics include solar collector panels, liquid crystal display screens, high-temperature lamp envelopes, and magnetic disk substrates. Glass-ceramics based on perovskite crystals are characterized by their unusual dielectric and electrooptic properties. Examples include highly crystalline niobate glass-ceramics that exhibit nonlinear optical properties, as well as titanate, niobate, and tantalate glass-ceramics with very high dielectric constants.
