A method for producing ceramic dielectrics containing a water soluble metal acid or salt includes making a mixture by kneading a water soluble metal acid or salt, particulates, sintering auxiliaries and water, mixing the mixture with a binder and plasticizer to form a slurry, and forming a sheet from the slurry by drying and sintering.

Method for producing ceramic dielectrics

A ceramic substrate is a high-temperature fired body consisting of alumina as the main component, zirconia, and a ceramics sintering assisting agent. The assisting agent is one of yttria, calcia, magnesia, and ceria, in which yttria is added at 0.1-2 wt %, calcia is added at 0.02-0.5 wt %, magnesia is added at 0.02-0.4 wt %, and ceria is added at 0.02-0.5 wt %.
