Abstract
A low-T
g SnO–MgO–P2O5 (SMP) glass was mixed with polytetrafluoroethylene (PTFE) to form composites by a sintering route. Effects of SMP:PTFE ratio and sintering temperature (350 °C–430 °C) on the microstructure and the bonding ability to a low thermal-expansion glass substrate were investigated. The onset softening temperatures of SMP and PTFE are close (328 °C and 313 °C), which are much lower than the onset temperature of weight loss of PTFE (381 °C). This is important for the sintering of SMP–PTFE composites. After sintering, pure SMP glass was not able to bond to the low thermal-expansion 1737® glass substrates. However, SMP–PTFE composites were able to bond to 1737® after sintering at appropriate temperatures. A possible mechanism for the enhancement of bonding by adding PTFE is discussed.
