Resistance to impact of porcelain stoneware tiles
Ceramics International, 2016The impact resistance of ceramic tiles is an important technical requirement, especially for large size and/or low thickness slabs. The standard test for ceramic tiles (ISO 10545-5) is non-destructive: it determines the coefficient of restitution of a small sample (75 x 75 mm(2)) assembled on a concrete substrate under a weak impact energy (0.27 J ...

Influence of Strengthening Components on Industrial Mixture of Porcelain Stoneware Tiles
Key Engineering Materials, 2004A typical industrial formulation for porcelain stoneware tiles was modified by adding synthetic mullite, and mullite-precursors, such as kaolin and gibbsite in order to enhance the mechanical properties by increasing the mullite content. The change in the physical properties as well as the technological and mechanical behaviour were evaluated on the ...

Process of pyroplastic shaping for special-purpose porcelain stoneware tiles
Ceramics International, 2009A novel technique to manufacture special-purpose tiles (i.e. trim pieces, steps, skirting boards, etc.) has been recently developed on the basis of a pyroplastic shaping of porcelain stoneware tiles. This innovative process involves a second firing, peaking at temperatures close to those of sintering, whose effect was investigated by comparing ...

Elastic properties of porous porcelain stoneware tiles
Ceramics International, 2017Abstract Porcelain stoneware tiles are industrially processed by using high sintering temperatures and fast firing cycles that result in products characterized by an almost impervious surface layer surrounding a rather porous bulk material. Since mechanical properties are affected by porosity, the knowledge of the material stiffness is an important ...

Reuse of solid petroleum waste in the manufacture of porcelain stoneware tile
Journal of Environmental Management, 2013This study investigates the incorporation of solid petroleum waste as raw material into a porcelain stoneware tile body, in replacement to natural kaolin material by up to 5 wt.%. Tile formulations containing solid petroleum waste were pressed and fired at 1240 °C by using a fast-firing cycle.

The Influence of Magnesium Silicates on Technological Behaviour of Porcelain Stoneware Tiles
Key Engineering Materials, 2001The influence of magnesium silicates, as sintering promoters, on the technological behaviour of porcelain stoneware tiles has been investigated. Three different raw materials formulations were studied: a typical industrial body, containing sodium feldspar as flux, and two alternative mixtures containing talc or chlorite as magnesium source, in partial ...

The use of nepheline-syenite in a body mix for porcelain stoneware tiles
Ceramics International, 2005In the study, the possibility to use nepheline-syenite, as fluxing agent, in a body mix used for porcelain stoneware tile, was determined. Starting from the reference mix composition, different amounts, 5.0, 10.0 and 15.6 wt.%, of sodium feldspar were replaced with the same amounts of nepheline-syenite.

Wear Resistance and Stain Resistance of Porcelain Stoneware Tiles
Key Engineering Materials, 2001The objective of the investigation was to study the mechanisms causing material transfer phenomena during dynamic interaction between porcelain stoneware tile surfaces and different kinds of materials. Tribological tests were carried out using a pin-on-disk apparatus with disks cut from different commercial porcelain stoneware tile samples coupled with

Recycling of polishing porcelain stoneware residues in ceramic tiles
Journal of the European Ceramic Society, 2007The possibility of recycling residues, coming from the industrial polishing process of porcelain stoneware tiles, by their incorporation in a porcelain stoneware body mix, was studied. Starting from a standard body mix, several modified body mixes were prepared by replacing different amounts of the fluxing component, a sodium feldspar sand, with these ...

Micromechanics Principles Applied to Fracture Propagation in Porcelain Stoneware Tiles
2008The possibility of discussing the mech. properties of porcelain stoneware tiles with a scientific approach typically used in the investigation of the composite materials is studied. A thorough microstructural investigation was conducted to det. if the addn. of selected low-cost minerals would improve mech. properties.
