Glass conduction

Specific conductance was measured with a Beckman conductivity bridge, Model RC-1682, and a dipping glass conductivity cell with a cell constant near 1 cm 1. This equipment was calibrated periodically in a standard KC1 solution. Conductance values were corrected to 25°C and are probably accurate to within 2%. 

An added benefit of using the ion trap for IMS studies is that non-conductive plain glass slides can be employed, since this mass analyzer does not rely on the initial kinetic energy of the ions. In an initial study to compare the use of indium-tin oxide coated glass (conductive) to plain glass slides, identical mass spectral correlation and image production for phospholipids were observed [4]. This result may offer the ability to analyze archived samples that probably would have been prepared on plain glass microscope slides and to reduce the costs of sample preparation. 

Why don t substances like glass conduct electricity as metals do Figure 6.32 provides an answer to this question. Basically, the electrical conductivity of a solid depends on the spacing and the state of occupancy of the energy bands. In magnesium and other metals, the valence bands are adjacent to the conduction bands, and, therefore, these metals readily act as conductors. In glass, on the other hand, the gap between the valence band and that... 

Related glass-conducting-polymer composites have also been recently prepared by other methods, more particularly for NLO applications [130,131].

Insulated glasses allow for reducing heat transfer which occurs by radiation, conduction and convection. Through the use of insulated glass units with a low-conductivity gas fill between two or three panes of glass, conductive and convective heat loss can be significantly reduced (Figure 4.3). 

Electrical heating is used extensively and exclusively in smaller speciality and fibreglass melting units because of its lower initial cost and low emissions as compared to combustion furnaces even though energy costs remain high. This drawback is compensated by flexibility in particular when small production volumes are required for speciality products. Glass conductivity plays an important...
