THERMAL ACCUMULATION-TRANSMISSION PANEL AND THE PROCESS FOR OBTAINING IT

摘要

The present invention relates to a thermal accumulation-transmission panel that comprises an improved porcelain stoneware and a manufacturing process thereof, for its use as a thermal accumulator and transmission element in heating devices. The thermal accumulation-transmission panel of porcelain stoneware of the invention is characterised in that it comprises a porcelain stoneware whose chemical composition comprises between 80.0% and 90.0% SiO2 and between 5.0% and 15.0% Al2O3, in that its geometry presents parallelepiped projections on one of its faces that permit the creation of natural convection chimneys and in that it has a thickness of at least 12 mm.
