Abstract

Sinterized vitroceramics for ceramic claddings with a high esthetic appeal are commercially manufactured by a single company in the world, the Japanese firm Nippon Electric Glass (NEG). The main commercial vitroceramic product for cladding is composed of the pseudo-wollastonita crystalline phase, an acclaimed success, but of restricted use owing to the high price. Currently we are witnessing a wild international chase after new compositions of sinterized vitroceramic with a more accessible price, with impact equivalent to that of porcelained gres, in applications such as floor and wall claddings, in addition to many others. The intention of this project is to develop a material for use in ceramic claddings obtained by the sinterization and crystallization of glass particle compacts. Its main phase should differ from that used by NEG, namely, a complex pyroxene of calcium, magnesium, silicon and aluminum, which displays promising properties for the applications mentioned, such as extreme hardness, resistance to abrasions and chemical resistance. Despite the technological advance in processes for the manufacture of sinterized vitroceramics, the technique is still far from saturation and is open to alternative processes and formulations. (AU)
