Plasma vitrification is a safe technique for eliminating the environmental impact of asbestos-containing materials. Additional advantages may arise from the obtainment of valuable ceramics from vitrified waste, if low cost treatments, comparable to those applied to traditional ceramics, are feasible. In the present paper the application of a fast heating rate (40°C/min) to produce dense sinter-crystallized materials from vitrified asbestos-containing waste, having a strength in excess of 100 MPa, is discussed. Sinter-crystallization, with fast heating processes, constituted also the basis of cellular glass-ceramics and a new type of stoneware, with waste glass replacing conventional feldspar fluxes.

Abstract
Plasma vitrification is a safe technique for eliminating the environmental impact of asbestos-containing materials. Additional advantages may arise from the obtainment of valuable ceramics from vitrified waste, if low cost treatments, comparable to those applied to traditional ceramics, are feasible. In the present paper the application of a fast heating rate (40°C/min) to produce dense sinter-crystallized materials from vitrified asbestos-containing waste, having a strength in excess of 100 MPa, is discussed. Sinter-crystallization, with fast heating processes, constituted also the basis of cellular glass-ceramics and a new type of stoneware, with waste glass replacing conventional feldspar fluxes.Pubblicazioni consigliate
