Process for producing a raw material powder to grow a single crystal and the single crystal |
摘要 |
In a process for producing a raw material powder comprising lithium potassium niobate for growing a single crystal of lithium potassium niobate, starting raw materials comprising lithium carbonate powder, potassium carbonate powder and niobium pentoxide powder are mixed in a solvent, lithium carbonate powder and potassium carbonate powder are entirely dissolved into the solvent, lithium carbonate and potassium carbonate are deposited around niobium pentoxide powder by spray-drying the mixture to obtain granulated powder, and then the granulated powder is thermally treated to produce the raw material powder. |
