- 13. The method of claim 10, wherein the cores comprise a plastic.
- 14. The method of claim 10, wherein the cores comprise carbon.
- 15. A discrete material for forming a sealing member, comprising:
- a plurality of pellets, each pellet comprising a ceramic core and a carbon based material coating which envelops said ceramic core, wherein the carbon based coating has a thickness of not less than one-half a diameter of the core.
- 16. The discrete material of claim 15, wherein the cores are substantially spherical.
- 17. The discrete material of claim 16, wherein the cores have a diameter no less than 0.5 mm.
- 18. The discrete material of claim 15, wherein said pellets have a diameter not greater than 15 mm.
- 19. The discrete material of claim 18, wherein said pellets have a diameter within a range of 1 to 12 mm.
