MANUFACTURE AND PROPERTIES
According to the material classification system for ceramics, silicon carbide ceramic forms part of the group of non-oxide ceramics. Two types are available:
- The base materials are high-grade silicon carbide raw materials, silicon dioxide (SiO2), and aluminium oxide
- Special quality through a silicon nitride compound (Si3N4)
SiC granules are mixed with temporary and permanent bonding agents. They are manufactured in a dry, semi-dry, or compression process. Formpieces are shaped by casting, followed by a sintering process.
- Excellent resistance to temperature fluctuations
- High temperature resistance
- High degree of hardness
- High thermal conductivity
- Corrosion resistance
- Max. service temperature limit, depending on the quality, up to 1.700°C
PRODUCT RANGE AND FORMATS
Depending on the production process, simple or complex geometric shapes (similar to cast metal elements) are possible, as are parts with large surface areas (1 m2) or smallest-scale parts.
- Formpieces and pipes (casting process)
- Wall thicknesses ranging from 10 to 75 mm (min. 6 mm)
- Possible formats of the formpieces: max. length 1.200 mm, max. width 1.000 mm, max. thickness 75 mm, min. thickness 6 mm (depending on the overall dimensions)
