Mullite is an excellent material
choice in high temperature, high hot strength, and thermally
shock resistant
products. It is virtually volume stable at very
high temperatures reaching 3100°F (1700°C). It has a
low coefficient of thermal expansion. It is a good thermal
and electrical insulator – even
at very high temperatures. It has outstanding
hot load-bearing properties, and it is resistant to
many corrosive environments.
It is, in short, the key ingredient in
many refractory and ceramic products.
Major Properties:
- Good high temperature strength
- Good thermal shock resistance
- Excellent thermal stability
- Resistance to most chemical
attack; it has excellent stability in acid metal slags
and is insoluble in most acids
- Resistance to oxidation
and attack by furnace atmospheres
- Resistance to abrasion
- Good electrical resistivity

QUARTZ TUBES
The industry-standard clear fused quartz material is economical
and available in a range of sizes. Quartz tubes have excellent
visual, thermal, and mechanical properties, low hydroxyl content
and tight dimensional tolerances.
Electrical Properties:
Fused quartz has many properties that make it an excellent choice
for electrical applications, very low electrical conductivity,
high dielectric strength and low dielectric loss. These properties
are maintained even at high temperatures.
Quartz has an annealing point of 1200°C and high resistance
to thermal shock – making it an excellent choice for many
heating applications, especially those with rapid temperature
cycle requirements.
