Glass-based materials

Unlike conventional ceramic materials, glass-ceramics are fully densifted with zero porosity. They generally are at least 50% crystalline by volume and often are greater than 90% crystalline Other types of glass-based materials that possess low amounts of crystallinity, such as opals and mby glasses, are classified as glasses and are discussed elsewhere (see Glass). 

The output screen consists of a glass base material (sometimes also fiber optics), onto which fine particles of (Zn, Cd)S Ag+ or Gd202S Tb3+ are applied, usually by sedimentation, but also by brushing or spraying. Phosphors with an average particle size of 1.5-3 pm and a narrow particle size distribution are used. The thickness of the layer is ca. 5-10 pm. 

Bulk micromachining of glass-based materials is a simple, fast, and low-cost way to fabricate planar microfluidic devices. Here we present a fast...
