The Fluoro-Materials Group was established late 2007 in the Department of Chemical Engineering.  The initiative was introduced by the [http://www.dst.gov.za/other/gpc/DST%20Fluorochemical%20Expansion%20Initiative.pdf DST] through what is called the Fluorochemical Expansion Initiative.

South Africa has the second largest reserve of [http://en.wikipedia.org/wiki/Calcium_fluoride calcium fluoride] in the world and currently has the third largest mining operations.  Calcium fluoride or fluorspar is the most abundant, naturally occurring, form of fluoride.  It is also the starting point for the production of anhydrous [http://en.wikipedia.org/wiki/Hydrogen_fluoride hydrogen fluoride], [http://en.wikipedia.org/wiki/Fluorine fluorine], [http://en.wikipedia.org/wiki/Tetrafluoroethylene tetrafluoroethylene] and various other industrially important fluorides.
 +
 
 +
The Fluoro-Materials Group mainly focuses on research in the following areas:
 +
* Production and production technology of anhydrous hydrogen fluoride and fluorine.
 +
* Depolymerisation and polymerisation of [http://en.wikipedia.org/wiki/Polytetrafluoroethylene polytetrafluoroethylene].
 +
* Extraction of various metals from local ore and ore found in southern Africa.
 +
* Production of various polymers, other than PTFE, by means of co-polymer additions to tetrafluoroethylene.

Introduction

The Fluoro-Materials Group was established late 2007 in the Department of Chemical Engineering. The initiative was introduced by the DST through what is called the Fluorochemical Expansion Initiative.

South Africa has the second largest reserve of calcium fluoride in the world and currently has the third largest mining operations. Calcium fluoride or fluorspar is the most abundant, naturally occurring, form of fluoride. It is also the starting point for the production of anhydrous hydrogen fluoride, fluorine, tetrafluoroethylene and various other industrially important fluorides.

The Fluoro-Materials Group mainly focuses on research in the following areas:

  • Production and production technology of anhydrous hydrogen fluoride and fluorine.
  • Depolymerisation and polymerisation of polytetrafluoroethylene.
  • Extraction of various metals from local ore and ore found in southern Africa.
  • Production of various polymers, other than PTFE, by means of co-polymer additions to tetrafluoroethylene.
