Can Cleansing Regimens Effectively Eliminate Saliva Contamination from Lithium Disilicate Ceramic Surface?
(2017-03-01)
This study evaluated the effect of cleaning protocols on the bond strength of resin cement to glass-ceramic. Ceramic specimens (N=120, n=12 per group) were etched with hydrofluoric acid and rinsed with water. After saliva ...

Influence of post-etching surface treatment and thermo-mechanical cycling on fracture strength of ceramics
(Edizioni Minerva Medica, 2016-10-01)
BACKGROUNG: The aim of this study was to evaluate fracture strength of lithium disilicate-based ceramic crowns submitted to neutralization of hydrofluoric acid (HF) precipitates associated with ultrasonic bath and to ...
Extraction of niobium and tantalum from ferrocolumbite by hydrofluoric acid pressure leaching
(Elsevier Science, 2015-07)
Abstract Pressure acid leaching was used to extract niobium and tantalum from a ferrocolumbite ore. The leaching was carried out in a pressure reactor using hydrofluoric acid as leachant. Various parameters, such as ...
