Strontium carbonate → Sodium Sulfate

Participants

Reaction Steps

A method of making a yttrium tantalate phosphor, the method comprising forming an oxide mixture of yttrium oxide, tantalum oxide, and optionally strontium carbonate; adding a lithium sulfate-sodium sulfate mixed flux to the oxide mixture; and firing the mixture at a temperature and for a time sufficient to form the phosphor wherein the weight ratio of lithium sulfate to sodium sulfate is from about 1.0 to about 1.8.
