Soda-lime-silica

Platinum is a beautiful silvery-white metal, when pure, and is malleable and ductile. It has a coefficient of expansion almost equal to that of soda-lime-silica glass, and is therefore used to make sealed electrodes in glass systems. The metal does not oxidize in air at any temperature, but is corroded by halogens, cyanides, sulfur, and caustic alkalis. 

For the hard borosilicate glasses and the soda-lime-silica glasses this if around 0-0025 cal °C" cm sec. For vitreous silica (Vitreosil) in the transparent form it is 0-0025 up to 500°C, and 0-0035 from 500 to 1000°C for the translucent form it is 0-0033. 

I il a soda-lime-silica glass, containing magnesia and boric oxide 1 than 1 per cent), made by the General Electric Co. It is often ibed as GEC X.8. or simply as X.8. The linear coefficient of Jial expansion between 20 and 350°C is 9-65 0-10 x 10-. This I il available as tubing and rod in a wide range of sizes.

The phase structure of glasses has a significant effect on their physical properties, which is discussed below with reference to chemical durability. The magnitude of the phase separation can be altered by heat treatment, and enhanced or reduced by the addition of various oxides to the melt. In particular, the addition of alumina to commercial soda-lime-silica glasses reduces the tendency to phase separation, improving chemical resistance (Doremus, 1973). A detailed study of the microstructure of soda-lime-silica glasses has been published by Burnett and Douglas (1970). The control of phase separation in the melt is now commercially important for processes such as the...

Soda-Lime-Silica Glasses. This is the most important group in terms of tonnage melted and variety of use. The combination of silica sand, soda ash. and limestone produces a glass that is easily melted and shaped and has good chemical durability. The raw materials are indigenous to most areas of the world and inexpensive. Soda-lime glasses are particularly suited...
