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
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.
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.
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.
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.
