Porcelain stoneware tiles with antimicrobial action

Ceramics International, 2014
Abstract This work reports the development of extruded porcelain stoneware tiles that show antimicrobial (to act as a barrier to the bacteria's growth during a long period of time), and anti-stain (easy to clean) actions, and possess high chemical resistance.

Porcelain stoneware consolidation by flash sintering

Journal of the American Ceramic Society, 2017
Abstract Porcelain stoneware was consolidated by flash sintering under DC polarization using current densities in the range 4‐20 mA/mm 2 . The results show the applicability of this innovative sintering technology to a material whose densification occurs by vitrification ...

Lightweight Porcelain Stoneware by Engineered CeO₂ Addition

Advanced Engineering Materials, 2010
AbstractThe use of porcelain stoneware in innovative applications such as the covering of internal walls or the manufacturing of ventilated facades may be limited by its relatively high density. In this paper, we discuss the achievement of a reduction in density of about 30%, coupled to a limited water absorption (about 2%), by the addition of CeO2 to ...

The reliability of polished porcelain stoneware tiles

Journal of the European Ceramic Society, 2005
The flexural strength and the Young’s modulus of as fired and polished porcelain stoneware tiles were investigated. Bending tests were carried out on suitable specimens, cut from five commercial products before and after polishing. The differences found in the flexural strength data were evaluated by the analysis of variance and the determination of ...

Double pressing for porcelain stoneware tiles: an exploratory analysis

Industrial Management & Data Systems, 2008
PurposeDouble pressing systems have recently been introduced to speed up and improve the pressing step of porcelain stoneware tiles. This paper aims to analyze double pressing systems using discontinuous pre‐compaction, both technically and economically.

Resistance to impact of porcelain stoneware tiles

Ceramics International, 2016
The 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 ...

Elastic properties of porous porcelain stoneware tiles

Ceramics International, 2017
Abstract 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 ...

Influence of Strengthening Components on Industrial Mixture of Porcelain Stoneware Tiles

Key Engineering Materials, 2004
A 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 ...

PORCELAINIZED STONEWARE TILE

1995
Dense, low-porosity, small-pore-size tile can be manufactured from kaolin clays at maximum firing temperatures. The unglazed porcelainized stoneware tile can be used for exterior applications and as frost-resistant materials.

Porcelainized stoneware: processing and characteristics

2003
Unglazed fast fired porcelainized stoneware tiles, for pavering and for exteriors, are the main innovative products present on the tile market. They are prepared using mainly kaolinitic clays, quartz and large amounts of fluxes to increase the sintering.
