Glazed ceramic floor tiles are ubiquitous
today, seen in homes and office buildings, in shops and in restaurants,
but the available market glazes have low abrasion resistance, meaning
tile surfaces can scratch fairly easily, incurring replacement and
The aim of this project was to obtain
a smooth ceramic surface glaze with improved hardness and wear resistance
properties. All new ceramic frits were developed. These are special
materials for preparing glass-ceramic glazes with excellent mechanical
and optical properties. These new materials, based on innovative
gahnite crystallisation, display oxide percentage compositions never
before seen in the ceramics industry and their development involved
extensive experimentation with crystalline-phase sintering and devitrification
kinetics during the firing of test specimens. New methodologies
were also developed for improving other glass-ceramic glazes and
for formulating new frits.
The new glaze is the best glossy, smooth,
white glaze ever seen on the market, meaning the industrial project
partners now have a competitive edge in the tile production sector.
The new glazed tile is more durable and has a higher life expectancy.
It was successfully launched on the market six months after the
end of the project.
