Low (and negative) thermal expansion Al2TiO5 materials and Al2TiO5 - 3Al2O3.2SiO2 - ZrTiO4 composite materials. Processing, initial zircon proportion effect, and properties
(Elsevier, 2018-12)
Aluminum titanate (Al2TiO5) materials and aluminum titanate - mullite- zirconium titanate (Al2TiO5 - 3Al2O3.2SiO2 - ZrTiO4) composite materials were successfully processed from fine commercial powders and characterized. ...
Internal Residual Stresses in Sintered and Commercial Low Expansion Li(2)O-Al(2)O(3)-SiO(2) Glass-Ceramics
(WILEY-BLACKWELL, 2011)
We performed Synchrotron X-ray diffraction (XRD) analyses of internal residual stresses in monolithic samples of a newly developed Li(2)O-Al(2)O(3)-SiO(2) (LAS) glass-ceramic produced by sintering and in a commercial LAS ...
Dense alumina-mullite composite ceramics from alumina and spodumene-albite feldspar binary mixtures: Processing and properties
(Int Inst Science Sintering (i I S S), 2020-05)
A processing strategy for obtaining alumina-spodumene ceramics from fine commercial powders is presented. In this work, a spodumene addition to calcined alumina powder was performed and their proportion was explored between ...
Sinterização, cristalização, desenvolvimento e caracterização de vitrocerâmicas de baixo coeficiente de expansão térmica do sistema Li2O - Al2O3 SiO2 (LAS)
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, 2010-10-15)
Glass-ceramics based on the Li2O-Al2O3-SiO2 (LAS) system represent the most important (commercial) family. They are required for applications where extreme dimensional stability and thermal shock resistance are of utmost ...
