Pyrophillite is a natural rock carefully selected in quarries. Its chemical make-up is very close to traditionnal ceramics.
This natural ceramic makes it possible to machine small parts at cold temperature and then to anneal them at 1050°c or 1300°c depending on usage conditions.
Chemical composition: Red loss: 4.69%, SiO2 : 63.79%, Al2O3 : 27.83% ,TiO2 : 0.41%, Fe2O3 : 0.048%, CaO : 0.10%, K2O : 2.96%, Na2O : 0.25%
High chemical purity
Very weak expansion coefficient
Very high thermal shock resistance
Working temperature : 1050°c
Peak temperature lapses: 1200°c
