Title:
METHOD FOR MANUFACTURING LITHIUM-ION-CONDUCTING GLASS CERAMIC
Document Type and Number:
WIPO Patent Application WO/2014/034482
Kind Code:
A1
Abstract:
This invention has: a step for forming a particulate using a raw material including a SiO2 source, a ZrO2 source, a P2O5 source, and a Na2O source; a step for causing the particulate to pass through a heated gas-phase atmosphere and thereby causing the particulate to melt and then solidify into a powder having a glass phase, the powder containing 20 to 60% of SiO2, 5 to 45% of ZrO2, 3 to 30% of P2O5, and 15 to 45% of Na2O (all figures representing the oxide-basis molar percentage); a step for heat-treating the powder and causing a crystal to be deposited to yield a processed body including a glass ceramic; and a step for performing ion exchanging on the processed body in a molten salt containing lithium ions to yield a lithium-ion-conducting glass ceramic.
