Refractory high strength Mullite kiln tray for high temperature
furnace
1.Description of Mullite kiln tray
Mullite or porcelainite is a rare silicate mineral of post-clay
genesis. It can form two stoichiometric forms 3Al2O32SiO2 or 2Al2O3
SiO2. Unusually, mullite has no charge balancing cations present.
As a result, there are three different aluminium sites: two
distorted tetrahedral and one octahedral.
Mullite was first described in 1924 for an occurrence on the Isle
of Mull, Scotland. It occurs as argillaceous inclusions in volcanic
rocks in the Isle of Mull, inclusions in sillimanite within a
tonalite at Val Sissone, Italy and with emerylike rocks in
Argyllshire, Scotland.
Mullite is present in the form of needles in porcelain.
It is produced during various melting and firing processes, and is
used as a refractory material, due to its high melting point of
1840°C.
In 2006 researchers at University College London and Cardiff
University discovered that potters in the Hesse region of Germany
since the late Middle Ages had used mullite in the manufacture of a
type of crucible (known as Hessian crucibles), that were renowned
for enabling alchemists to heat their crucibles to very high
temperatures.
