FIRE CLAY Chemische Eigenschaften,Einsatz,Produktion Methoden
Beschreibung
Fireclay denotes a silica-rich natural clay that can withstand a high firing temperature above the pyrometric cone equivalent (PCE) of 19
without melting, cracking, deforming, disintegrating, or softening. Typically, a good fireclay
should have 24 to 26 vol.% plasticity, and shrinkage after firing should be within 6 to 8 vol.%
maximum. Fireclays are mostly made of kaolinite, but some Fe2
O3
and minor amounts of
Na
2O, K
2O, CaO, MgO, and TiO
2
are invariably present depending on the mineralogy and geology of the deposit, making it gray in color.
