MICA

Muscovite Mica has a long established history of use in rutile electrodes for steel.  The main beenfits of incorporating mica into the flux coatings for such electrodes are:

  • The plate shape of mica influences the rheology of the flux mix during the extrusion coating process.
  • Faster rates of drying and curing can be employed with a reduced risk of cracking
  • The elastic mica flakes toughen the flux coating and reduce damage during handling and transportation both before and after drying
  • Cracking is also reduced when electrodes are bent during use
  • The melting point of mica is beneficial for all types of steels
  • Mica offers a useful source of potassium without altering silicate binder chemistry

We are able to supply mica in any mesh size or normal specification so please contact us for any mica enquiries.
