Other | Typical characteristics of the Pyrophyllite material include: Machinable, thermally insulating, good thermal shock properties, good mechanical stability once fired. The key features of Pyrophyllite Heat Treated at 1250 °C - 1300 °C are: Good electrical properties in humid conditions, high abrasion resistance, will give <3µm surface finish, high dielectric strength, fair dielectric constant, high mechanical stability, only diamond grinding can be used to adjust sizes. Over 1000 °C a gradual shrinkage takes place and the machined component loses some of the volume expansion that has occurred. As the material densifies the sizes will return to within ± 1% of the machined sizes. Any size alteration will have to be carried out by wet grinding. Diamond with coolant is best but Green grit wheels suffice on prototypes. Always allow Furnace to cool naturally to 200 °C before removing parts. Never wet the unfired material for machining. Safe maximum operating temperature 1100 °C. |
