Title:
MANUFACTURE OF COMPOSITE FERRITE
Document Type and Number:
Japanese Patent JPH06244015
Kind Code:
A
Abstract:

PURPOSE: To produce a composite ferrite whose component ratio is substantially identical to a solution component by reducing a liquid drop size of an aqueous solution which contains more than two kinds of metal ions below a specific dimension.

CONSTITUTION: An aqueous solution, which contains more than two kinds of metal ions, is atomized where the liquid drop size of liquid drop particles at that time is specified to be 150μm and below. The thermal energy of combustion gas generated at a burner is supplied to this aqueous solution, thereby evaporating the water content of the liquid drops, thereby allowing residual metal salt particles to produce thermal cracking or chemical reaction with the thermal energy. During this time, the water content of the atomized liquid drop particles are evaporated spontaneously, thereby producing quick roasting. This construction makes it possible to obtain a composite ferrite whose component ratio is substantially identical to a solution component.
