ているものと思われる。It is unknown why ceramics can be easily obtained by mixing this ceramic, but according to the results of X-ray diffraction, diffraction peaks derived from calcium phosphate, which are not observed in the original components, were observed from the X-ray diffraction. Talc [Mg 3 Si 4 O 10 (OH) 2 ], kaolin [Al 4 Si
Since diffraction peaks of 4 O 10 (OH) 8 ], calcium carbonate [CaCO 3 ], etc. have almost disappeared, a phosphate glass having a relatively low melting point is generated, which greatly contributes to firing of the vitreous component. It seems to be.
また、セラヒートは、一度焼成したセラミックを微粉
