Zusammenfassung:PURPOSE:To maintain characteristics and function of mica without the presence of foreign materials by applying a slurry substance of mica composition to collected mica films consisting of fluophlogopite, laminating the obtained films, calcining the resultant laminate and forming a new mica between layers. CONSTITUTION:One or more are selected from silica sol, alumina sol, potassium silicate and lithium silicate prepared by forming SiO2, Al2O3 K2O and Li2O into sols. The resultant sols are then mixed with other oxides and fluorides required to synthesizer a mica to provide a slurry substance, which is then used as a binder and applied to collected mica films consisting of fluophlogopite and laminated. The resultant laminate is then calcined to crystallize the above- mentioned binder and form the new mica between mutual films. Thereby, a mica ceramic laminated together with the fluophlogopite is formed.
