Dense shaped articles of polycrystalline β-silicon carbide and process for the manufacture thereof by hot-pressing |
| abstract |
The invention relates to dense shaped articles of polycrystalline beta -silicon carbide containing small amounts of aluminum and optionally, nitrogen and/or phosphorus, having a virtually single-phase microstructure since the additional constituents are substantially in the form of a solid solution in the beta -SiC lattice. The shaped articles are characterized by high temperature flexural strengths of at least 600 N/mm2 at temperatures up to 1450 DEG C. The fracture mechanism is transgranular up to at least 1450 DEG C. The shaped articles are manufactured by hot-pressing and simultaneously shaping pulverulent beta -silicon carbide with small amounts of an aluminum-containing additive, such as aluminum powder or aluminum nitride and/or aluminum phosphide, at temperatures between 1750 DEG C. and 2200 DEG C. under a pressure of at least 100 bar (10 MPa). |
