    摘要: IN MAKING LITHIUM FERRITES WHEREIN LITHIUM CARBONATE OR OXIDE IS COMBINED WITH AN IRON OXIDE, PROCESSING TIME IS MATERIALLY REDUCED BY INCORPORATING LITHIUM CHLORIDE IN THE MIXTURE. THE LITHIUM CHLORIDE CAUSES THE LITHIUM CARBONATE TO BECOME VERY REACTIVE AND ATTACK THE IRON OXIDE RAPIDLY. AFTER FIRING TO FORM THE DESIRED LITHIUM FERRITE, THE LIHTIUM CHLORIDE IS DISSOLVED OUT OF THE MASS WITH WATER OR OTHER SOLVENT.
