13. Characterization and Evaluation of Ceramic Properties with Spherical and Prismatic Samples of Clay Used in Red Ceramics
The Brazilian red ceramic industry monthly consumes about 10.3 million tons of clay, its main raw material. In most potteries, characterization of the clay is made empirically, which can result in roof tiles and blocks not according to standards. In this sense, this paper aims to characterize clays used in the manufacturing of red ceramic products in a facto

16. Influence of surrounding wall thickness on the fatigue resistance of molars restored with ceramic inlay
The purpose of this study was to evaluate the influence of buccal and lingual wall thickness on the fatigue resistance of molars restored with CAD/CAM ceramic inlays. Forty human third molars were selected and divided into 4 groups, according to the remaining surrounding wall thickness chosen for inlay preparation (n = 10): G1, 2.0 mm; G2, 1.5 mm; G3, 1.0 mm

17. Effects of cement-curing mode and light-curing unit on the bond durability of ceramic cemented to dentin
The aim of this study was to evaluate the effects of different light-curing units and resin cement curing types on the bond durability of a feldspathic ceramic bonded to dentin. The crowns of 40 human molars were sectioned, exposing the dentin. Forty ceramic blocks of VITA VM7 were produced according to the manufacturer's recommendations. The ceramic surface

18. Influência da adição de nanopartículas de TiO2 na obtenção de compósitos a base de liga AA2014 fabricada via metalurgia do pó / Influence of the addition of TiO2 nanoparticles in the composites formation based AA2014 alloy manufactured by powder metallurgy
Aluminum matrix composites and its alloys, especially AA2014, are widely used in automotive and aeronautics applications. The properties of this are very influenced by hardening treatment, however its use is limited at temperatures above 150C due to loss of properties caused by the growth of precipitates at this temperature. The addition of a new phase, fine

19. Desenvolvimento e caracterização de microesferas de fosfato de cálcio bifásico / Development and characterization of biphasic calcium phosphate microspheres
The biphasic calcium phosphate is greatly applied in the replacement of osseous tissues and as dermal fillers due to its chemical similarity with the mineral part of bone and teeth. Due to this similarity, the calcium phosphates present, among other important properties, high biocompatibility, bioactivity and/or osteoconduction. They do not induce inflammato
