Sodium feldspar is used
as a flux in ceramics manufacturing, especially for the production
of porcelain stoneware, sanitary pottery and glazes. The ceramics
and glass industry is the biggest user of albeit in its various
production segments. The fast growth in this market over the last
ten years is partially due to the great availability of mineral
resources within the Indian territory and to Galaxy Group constancy
in terms of product quality, quantity and diversity. Galaxy Group
production meets a significant slice of sodium feldspar needs for
tile production and supplies almost the entire Indian sanitary
pottery industry. Outside of Indian important European ceramics
groups traditionally use Galaxy sodium feldspar in order to
guarantee the product quality demanded by international standards.
Melting at a lower temperature than the other components in the mix,
albeit lowers the overall fusion point. It attacks and brings into
solution other components in vitrified products, with quantities
depending on temperature and firing time.
A good deal of the final characteristics of the various ceramic
products depends on the type and quality of the feldspar used.
Depending on the percentage used, the firing process and the
composition of the other components, albeit favors the
solubilization of the raw materials creating a liquid phase around
the solid particles.
Chlorite albites, produced by Galaxy Group, meet the ever growing demand for powerful fluxes that allow the mixtures to sinter at lower temperatures. In the tile industry, where there is a trend towards increasingly short firing times, the addition of magnesium to feldspar gives the finished product a coherence equal to or greater than that of products obtained with longer firing times using traditional feldspars.
