PYROPHYLLITE

DATA SHEET: PYROPHYLLITE

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.


Basic properties:

• Good electrical insulator

• Low dielectric loss

• Resists to chemicals

• Stability and precision of shapes

• Resistant to high temperature

• Excellent resistance to deep vacuum

• Good resistance to thermal shock

• Very low thermal expansion when heated to 1050°C

Applications

• Electrical engineering

• Scientific research

• Prototype parts and small series of insulating parts

• Used to make small laboratories furnaces

• Wear parts (sanding tubes, casting nozzles

• MIG and TIG welding nozzle

• Plasma nozzles

• Welding assemble support and positionning templates

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%
