A bstract The compositions are given for high‐titania ceramic bodies which mature at cone 10. One series contains calcium titanium silicate as an essential flux, and the other series contains alkali‐free titania glasses. Electrical measurements cover the range of 60, 1000, and 1,000,000 cycles for both power factor and dielectric constant. Detailed consideration is given to the type of electrodes used. The properties covering dielectric strength, temperature coefficient of capacity, effect of humidity, and thermal expansion are given for one composition. An X‐ray diffraction pattern of this body shows the formation of rutile crystals.
