Structural studies and electrical properties of recycled glasses from glass and incinerator wastes

The electrical behaviour of different glass compositions obtained from mixi ng waste glass deriving from a community glass recycling program and silica te waste from the incineration of municipal solid residues (from Reggio Emi lia city) have been investigated as a function of temperature and frequency . The electrical and dielectric properties were related to structural studi es performed on the same glassy materials. As the amount of incinerator was tes increases, on account of lower alkali and higher alkaline-earth content in the final glass composition, conductivity and dielectric losses decreas e approaching the behaviour of type E glass fibres, so envisaging a possibl e use of waste-containing glasses in the production of high voltage insulat ors.
