Microestrutura e propriedades mecânicas de vitrocerâmicos do sistema Li2O – CaO – SiO2
(Universidade Federal de São Carlos, 2013-03-12)
An interesting characteristic of the Li2O-CaO-SiO2 glass-forming system is the possibility of obtaining certain crystalline phases and morphologies that may lead to tough glass-ceramics. However, very few published works ...
Avaliação de modelos de sinterização por fluxo viscoso e determinação da taxa de crescimento de cristais e fração cristalizada em vidros
(Universidade Federal de São Carlos, 2012-08-16)
Glass-ceramics are materials obtained from the controlled crystallization of glass. The properties of these materials are controlled by the nature and proportions of the crystalline phases and residual glass present. ...
Nucleação, crescimento de cristais, relaxação e escoamento viscoso em vidros de diopsídio e diborato de lítio
(Universidade Federal de São Carlos, 2014-04-23)
Heated glasses undergo a variety of kinetic processes, such as crystallization, relaxation and viscous flow, that are very important both scientifically and technologically. In this work, we measured and rigorously analyzed ...
Processos difusionais, cristalização e escoamento viscoso em dissilicato de bário vítreo
(Universidade Federal de São Carlos, 2014-04-24)
In this work, we analysed if the viscous flow successfully describes the transport of crystal nucleation and crystal growth structural units that occur at the liquid/crystal interface. In order to do this, we calculated ...
Cristalização e sinterização de bio vidros do sistema Na2O-CaO-SiO2-P2O5
(Universidade Federal de São Carlos, 2001-03-30)
The objective of this work was to study crystallisation and sintering of Bio-glasses of Na2O CaO SiO2 P2O5 aiming at the improvement of the mechanical properties. In order to study the development of glass-ceramics in this ...
