Porcelain tiles were invented in Italy more than 30 years ago. Originally it was used as a floor covering in public places with high traffic capacity: shopping and business centers, airports, hotels, metro- and train stations. It is for this purpose that the material is endowed with enhanced performance properties such as strength and durability. As the material was spread, porcelain tiles were used for facing facades of buildings, finishing the floor and also walls in apartment houses and apartments.
Porcelain tiles are made from a mixture of clay, sand, feldspar and natural coloring pigments. The mixture is pressed under very high pressure and is fired at very high temperatures (the highest in the ceramic industry). Raw materials are sintered, forming a monolith, in which there are no voids, cracks and foreign inclusions.
Basic properties of porcelain tiles:
Types of porcelain tiles
It does not have a decorative face layer and is painted in mass – for the entire depth of the product. Its structure is completely homogeneous, like the structure of natural stone. The density of ceramic granite of this type is also comparable to the density of a stone. In terms of hardness, unglazed ceramic granite is superior to the best grades of natural granite.
In its properties, this material occupies an intermediate position between unglazed ceramic granite and ceramic tiles of single firing. With the latter it is related buy technology of manufacturing: the enamel is applied to the front surface and is baked together with the tile in one step.
Borders and steps
Ceramic granite can be cut into pieces of any form on special machines with diamond cutters. As a result, decorative and special elements are obtained: curbs, inserts, mosaics, roseons, as well as skirting and steps.
