Silicium Subject

A good adhesion between the fibre and the resin is important. Usually, the glass fibres have already been subjected to a chemical treatment by their manufacturer in order to improve their adhesion. The most often used agents for this purpose are based on methacrylate-chromium compounds and on organic silicium compounds. 

Taking silica (bulk composition silicium oxide, Si02), from which capillary material in capillary electrophoresis (CE) is manufactured, as an example, one can readily understand this when taking into account that on the silica surface, there are silicium hydroxide groups that are subject to an acid-base equilibrium according to... 

Experimentally, the crystallization and the amorphization of binary amorphous systems under pressure have already been the subjects of many studies [73-81]. In 1965, Prewitt and Young [73] found two new crystalline phases of Germanium and Silicium disulfides at T=300 K under pressure. Later, Shimada and Dachille [74] studied the crystallization of amorphous GeSe2 under pressure and found that three different crystalline phases exist depending on temperature and pressure. They also quoted that the crystallization was inhibited for temperatures lower than T=573 K.
