- 3. A process according to claim 1, wherein said lithium orthosilicate particles contain up to 5 wt. % of aluminum, an aluminum compound, silicon, or a silicon compound or mixtures thereof.
- 4. A process according to claim 2, wherein said lithium orthosilicate particles contain up to 5 wt. % of aluminum, an aluminum compound, silicon, or a silicon compound or mixtures thereof.
- 5. A process according to claim 2, wherein said particles are substantially spherical.
- 6. A process according to claim 4, wherein said particles are substantially spherical.
- 7. A process according to claim 2, wherein said lithium orthosilicate particles contain 0.5-5 wt. % tellurium, a tellurium compound or mixtures thereof.
- 8. A process according to claim 3, wherein said lithium orthosilicate particles contain 0.5-5 wt. % tellurium, a tellurium compound or mixtures thereof.
- 9. A process according to claim 3, wherein said lithium orthosilicate particles contain up to 2.2 wt. % SiO.sub.2.
