Glass, limitations from corrosion

This burgeoning set of reviews serves as a starting point for our discussion of glass corrosion resistance, although our review differs from those noted above by emphasizing dissolution behaviour near saturation with respect to potential rate-limiting phases. 

The Charles-Hilling theory has been confirmed experimentally in soda-lime glass and alumina we can infer from known test results (Table 6.1.2) that the strength of brittle materials is limited by stress corrosion. 

The versatility of the glass-lined vessel in a large variety of chemical environments has made it the most common in the industry. For these reasons, a crystaUization step may be carried out in an equipment train in a glass-lined vessel whether or not this is required to prevent corrosion. These reactors range in size from 80 to 20,000 liters or more. One limitation in the use of glass-lined vessels related to mixing and heat transfer is that the limit of the temperamre difference between jacket and batch is 125 C. However, such temperature extremes... 

Although glass and plastic materials have been used for the fabrication of heat exchangers there are limitations to their use. In the former the problem of fragility exists and in the latter there are temperature restrictions. At the present time the majority of heat exchangers are usually fabricated from metallic alloys where corrosion is anticipated.
