Abstract
The invention relates to a high-performance compacted ceramic material, comprising between 40%-85% by weight of glassy phase, having a density between 2.3 and 3.0 g/cm3, and characterized in that it has an internal porosity of less than 4% by volume. This material is highly resistant to mechanical and chemical action, sparingly permeable and prevents staining, so it is extremely suitable as a building material, particularly for kitchen countertops.
Claims18
A compacted ceramic material comprising between 40%-85% by weight of glassy phase, having a density between 2.3 and 3.0 g/cm3, and an internal porosity of less than 0.5% by volume of the total volume of the material, wherein starting materials comprise potassium feldspar in a range of 15-25% by weight out of the starting materials, and sodium feldspar in a range of 35-45% by weight out of the starting materials, and wherein sodium feldspar and potassium feldspar comprise feldspar particles and at least 95% of the feldspar particles have a size of less than or equal to 40 μm.
