Wear properties of alpha- and alpha/beta-SiAlON ceramics obtained by gas pressure sintering and spark plasma sintering
(Elsevier Sci LTD, 2011)
In this study, alpha- and alpha/beta-SiAlON materials, doped with Y(2)O(3) and Nd(2)O(3), were sintered using two different sintering processes: spark plasma sintering (SPS) and gas pressure sintering (GPS). The wear and ...
Wear behaviour of alpha- and alpha/beta-SiAlON ceramics stabilized with Nd2O3 and Y2O3
(Elsevier Sci LTD, 2009)
alpha- and alpha/beta-SiAlON compositions, doped with Y2O3 or Nd2O3, were densified by gas pressure sintering (GPS). The wear and mechanical properties of the materials were investigated and compared to beta-Si3N4 materials. ...
The use of metarhyolites in porcelain stoneware production, Ilgin-Konya area, Turkey
(Techna Srl, 2010)
The aim of this study is to determine the properties of metarhyolites from Konya (Turkey) area and to decide whether or not metarhyolites are suitable as a flux agent for porcelain stoneware tile production For this aim, ...
The reaction kinetics of rice husk based cordierite ceramics
(Elsevier Sci LTD, 2008)
In this study, rice husk ash (RHA) was used as a silica source for cordierite production. Two different groups of samples were prepared in order to achieve the synthesis of cordierite. In the first group (HS-0), kaolinite, ...
A novel approach for synthesis of monticellite based bioactive ceramic powders from boron derivative waste
(Elsevier Science BV, 2017)
Monticellite bioactive ceramics have a high usage potential as bone graft substitutes due to their superior mechanical properties compared to hydroxyapatite and excellent bioactivity. Turkey has almost 72% of the global ...
The influence of different CaO source in the production of anorthite ceramics
(Elsevier Sci LTD, 2009)
The effects of starting raw materials and firing conditions oil anorthite (CaAl2Si2O8) phase formation are investigated by differential thermal analysis (DTA)-thermogravimetry (TG) and X-ray powder diffraction (XRD). Four ...
Utilization of a sandy clay in double-fired wall tile bodies
(Techna Srl, 2010)
In the production of ceramic tiles, composition of body and firing conditions determine the phase transformations and in turn affect the final properties of the product Thus, selection of relevant raw materials and ...
Co-doped willemite ceramic pigments: Technological behaviour, crystal structure and optical properties
(Elsevier Sci LTD, 2010)
Cobalt-doped willemite is a promising blue ceramic pigment, but some important aspects concerning crystal structure, optical properties and technological behaviour are still undisclosed. In order to get new insight on these ...
CVD growth of monolayer MoS2: Role of growth zone configuration and precursors ratio
(IOP Publishing LTD, 2017)
Single-layer, large-scale two-dimensional material growth is still a challenge for their wide-range usage. Therefore, we carried out a comprehensive study of monolayer MoS2 growth by CVD investigating the influence of ...
A critique of master sintering curve analysis
(Elsevier Sci LTD, 2018)
In this work, we explore factors affecting the accuracy of the master sintering curve (MSC) approach for analyzing the complete sintering profile of ceramic powders. We show that the instantaneous anisotropic shrinkage ...
