ALTRONTM
alumina-bonded silicon carbide (SiC) has been developed by Blasch
Precision Ceramics, Inc. The precision-cast shapes outlast nitride-bonded SiC
brick and wear-resistant alloys in mining, power generation and cement
processing applications.
Field
trials in hydrocyclone applications in mining and cement plants have shown more
than three times the life of conventional nitride-bonded SiC components. ASTM C
704 abrasion resistance testing has verified this.
The
new composition creates a unique interaction between constituent materials,
yielding a body with refractory-like densities that allows the shapes to be
thermal-cycled repeatedly without damage due to thermal shock, but with a very
closed porosity that is normally found in fully dense advanced ceramic bodies.
The
new material can be formed and processed like conventional nitride-bonded SiC,
but exhibits greater abrasion resistance in line with much more expensive and
difficult-to-form advanced ceramic materials.
Applications
for this composition include: slurry, ore, ash, coal, coke and catalyst processing
and transport in high-temperature, abrasive and corrosive environments. Typical
components include pipe linings, elbows, burners, valves, cones, vortex
finders, nozzles, micronizers and pump components.
