Mullite
Mullites (3Al2O3 + 2SiO2)
are refractory oxide materials combining low thermal expansion, good
mechanical strength and resilience at elevated temperatures.
Vesuvius McDanel mullites are formulated to produce dense shapes,
some in a glass matrix in order to yield maximum thermal shock
resistance and good strength.

Alumina
Aluminas (Al2O3) are generally more
chemically resistant, harder, stronger and more refractory than
mullite.

998
99.8% alumina can be used at operating temperatures to 1950¡É
in both oxidizing and reducing atmospheres. Tubes have been
evacuated to 10-7 Torr at 1500¡É. 998 proves inert
to hydrogen, carbon and refractory metals in many severe
situations. |

Zirconia
Zirconias (ZrO2) are extremely refractory
materials. They possess excellent chemical inertness and corrosion
resistance at temperatures well above the melting point of alumina.
Vesuvius McDanel zirconias are stabilized in the cubic crystal
structure to avoid cracking and mechanical weakening during heating
and cooling. In addition to their refractoriness, they offer low
thermal conductivity and are electrical conductors above 800°C. They
also possess the unique ability to allow oxygen ions to move freely
through the crystal structure above 600¡É.

Sialon
Vesuvius SiAlON is an alloy of silicon nitride and aluminum
oxide. This superior refractory material has the combined properties
of silicon nitride (high strength, hardness, fracture toughness and
low thermal expansion) and aluminum oxide (corrosion resistance,
chemically inert, high temperature capabilities and oxidation
resistance.
Most
refractory products are capable of surviving one or two specific
environments that typically involve high temperature, mechanical
abuse, corrosion, wear or electrical resistance. Vesuvius SiAlON has
the capability to withstand all of these environments - at the same
time!
