Because of their unique combination of physical and chemical properties, manufactured carbons and graphites are widely used in several forms in high temperature processing of metals, ceramics, glass, and fused quartz. A variety of commercial grades is available with properties tailored to best meet the needs of particular appHcations (45). Industrial carbons and graphites are available in a broad range of shapes and sizes. 

Shock Luminescence. Some transparent materials give off copious amounts of light when shocked to a high pressure, and thus they can serve as shock arrival-time indicators. A technique used by McQueen and Fritz (1982) to measure arrival times of release waves is based on the reduction of shock-induced luminescence as the shock pressure is relieved. Bromoform, fused quartz, and a high-density glass have been used for their shock luminescence properties. 

Photomultipliers of type S-19 employ fused quartz instead of UV glass this transmits down to /l = 160nm although this far UV range is not normally employed in scanners. 

Glass and fused quartz form one of the most inert surfaces with respect to heterogeneous de-excitation of 02( A ). The coefficient of heterogeneous decay of yin this event lies within lO - 10, depending upon the experiment conditions. As the temperature of glass walls increases, the y decrease by the law... 

Experiments on the studies of possible emission of active particles were conducted in a vial similar to that shown in Fig. 6.1. Chamber 2 was linked to the vacuum grinder. The grinder involved thick wall quartz test tube and a quartz piston (glass-covered iron weight). When pulse signals were fed to the coil of an electromagnet the piston rose by 2 - 3 cm and fell down. Such an instrument made it possible to grind quartz with substantial efficiency in a thick wall test tube made of fused quartz [61].

Amorphous silica, ie, silicon dioxide [7631-86-9]9 Si02, does not have a crystalline structure as defined by x-ray diffraction measurements. Amorphous silica, which can be naturally occurring or synthetic, can be either surface-hydrated or anhydrous. Synthetic amorphous silica can be broadly divided into two categories of stable materials (1) vitreous silica or glass (qv), which is made by fusing quartz at temperatures greater than approximately 1700°C (see Silica, vitreous silica), and microamorphous silica, which is discussed herein.
