The ideal material: Vitreous Silica
All our crucibles are essentially made of vitreous silica, which is nothing other than highly pure quartz sand melted at a temperature of more than 2000°C.
Vitreous silica has very interesting properties that fully justify its use in the production of dental crucibles:
Very low expansion coefficient, giving it an extraordinary resistance to thermal shocks.
Low sensitivity to metal oxides, ensuring lasting resistance to the corrosion caused by dental alloys.
More than 15 years ago, our company launched the use of vitreous silica in Europe for dental crucibles. Today, this material is used widely because it makes it possible to significantly lengthen the life of crucibles.
Céramiques et Réfractaires is ceaselessly looking for ever higher-performing materials. Studies are conducted every day to propose the very highest quality crucible on the market.
Characteristics and utilisation of our Crucibles for blowlamp melting
All our crucibles for blowlamp melting are made of vitreous silica.
With the exception of titanium, all types of dental alloy can be melted in these crucibles.
Precautions for use:
We recommend that you dry your crucibles thoroughly before using them for the first time.
