Claims
- 1. A holder for a sealing member, in which at least a portion of said holder which comes into contact with said member comprises a sintered body comprising as a main component a non-oxide ceramic of silicon nitride, aluminum nitride, sialon or silicon carbide finished to a grinding degree of less that 4 S wherein S indicates a surface roughness in accordance with Japanese Industrial Standard B 0601.
- 2. The holder for sealing member according to claim 1, wherein said sintered body comprises not more than 10% by weight of an oxide of a rare earth element and the balance consisting essentially of said silicon nitride.
- 3. The holder for sealing member according to claim 2, wherein said sintered body further comprises not more than 10% by weight of aluminum oxide, not more than 10% by weight of manganese monoxide and not more than 10% by weight of aluminum nitride.
- 4. The holder for sealing member according to claim 1, wherein said sintered body comprises 0.05 to 5% by weight of aluminum oxide, 0.05 to 6% by weight of aluminum nitride, 0.1 to 7% by weight of yttrium oxide and the balance consisting essentially of said silicon nitride.
- 5. The holder for sealing member according to claim 1, wherein said sintered body comprises not more than 10% by weight of an oxide of a rare earth element and the balance consisting essentially of said aluminum nitride.
- 6. The holder for sealing member according to claim 5, wherein said sintered body further comprises not more than 10% by weight of calcium, not more than 10%/by weight of strontium and not more than 10% by weight of barium.
- 7. The holder for sealing member according to claim 1, wherein said sintered body comprises not more than 10% by weight of an oxide of a rare earth element and the balance consisting essentially of said sialon.
- 8. The holder for sealing member according to claim 7, wherein said sintered body further comprises not more than 10% by weight of aluminum nitride, not more than 10% by weight of manganese monoxide and not more than 10% by weight of aluminum nitride.
- 9. The holder for sealing member according to claim 1, wherein said sintered body comprises at least one of 5% by weight or less of boron, 5% by weight or less of carbon and 5% by weight or less of aluminum compound and the balance consisting essentially of said silicon carbide.
- 10. The holder for sealing member according to claim 1, wherein said sealing member is a pin for cathode ray tube.
