Polymers containing radicals. A related problem arises from the way in which an in situ EPR cell is constructed. Many monomers polymerize via a radical mechanism and, although set and hard, the polymer may still contain traces of paramagnetic radical monomer species. For this reason, EPR cells tend to be constructed from silica and inorganic adhesives and cements. 

ZSM-5 was grown on the outer surface of a porous alumina tube by Matsuda et al. [45]. The tube was first sealed with an inorganic adhesive to avoid crystallization on the inner walls and subsequently vertically positioned in a ZSM-5 synthesis solution. Under stirring conditions at 200°C after 48 hours, a film was formed of ZSM-5 on the outer surface. The synthesis was repeated several times to obtain a 100 pm thick and dense layer. Finally, the zeolite composite phase was calcined.

These materials are widely used because they are durable, fire-resistant, and inexpensive when compared with organic materials. Inorganic adhesives are based on compounds such as sodium silicate, magnesium oxychloride, lead oxide (litharge), sulfur, and various metallic phosphates. The characteristics of some of the more important commercial materials are summarized. 

Special adhesives are required for high temperature use. Silicone rubber is an excellent flexible adhesive with a temperature limit of 250 °C. For higher operating temperatures, one must resort to inorganic adhesives and cements. These are usually based on silicates (water glass), phosphates (phosphoric acid), and Portland cement.
