Abstract
Polytetrafluoroethylene (PTFE) was ground with SrO using a planetary ball mill in air. The grinding stimulates the solid reaction between PTFE and SrO at room temperature. PTFE is decomposed by the solid reaction and fluorine in PTFE is transformed into strontium fluoride. The results show that it is possible to mineralize highly stable polymer PTFE by grinding with proper additive.Keywords
