Luminescent Er3+doped transparent alumina ceramics
We report on successful preparation of Er3+doped transparent alumina (0.1–0.17 at.%) exhibiting visible light photoluminescence using wet shaping method and hot isostatic pressing. The effects of dopantamount, type of ...
Optical, mechanical and fractographic response of transparent alumina ceramics on erbium doping
Alumina ceramics found their utilisation in many applications which can be further extend by attaining functional properties; in our case the transparency obtained through precise processing and photoluminescence due to ...
Master Sintering Surface – A Practical Approach to Its Construction and Utilization for Spark Plasma Sintering Prediction
(International Institute for the Science of Sintering, 2012-08-01)
The sintering is a complex thermally activated process, thus any prediction of sintering behaviour is very welcome not only for industrial purposes. Presented paper shows the possibility of densification prediction based ...
Luminescent Eu3+-doped transparent alumina ceramics with high hardness
The Eu3+-doped transparent aluminas were prepared by wet shaping technique followed by pressureless sintering and hot isostatic pressing. The effect of dopant amount on microstructure, real in-line transmission (RIT), ...
A Practical Approach for the Calculation of the Activation Energy of the Sintering
(International Institute for the Science of Sintering, 2016-12-15)
Newly developed software for calculation of activation energy (Qs in the following) of sintering using the Wang and Raj model is presented. To demonstrate the practical potential of the software and to evaluate the behaviour ...
