Abstract
The removal and destruction of ceramic fibers wastes are presently an important problem for the society health. Among these, the asbestos, which are silicates, is the more dangerous. Usually their destruction is obtained by a melting way, but this needs high temperature (about 1500-1600°C) and presents an expensive treatment. In this paper we show that the sodium polyphosphate addition to different asbestos (chrysotile, amosite and crocidolite) permits to obtain the fiber's destruction at a temperature below than 900°C. This process may be applied to composite materials containing a few part of asbestos, like carpet tiles or building plaster. This process of waste's treatment can open a new and a large market for sodium polyphosphate.
