1. A method of making a friable-resistant dielectric porcelain material, said method comprising:
providing an aqueous composition comprising water and either (A) or (B) as follows:
(A)feldspar at about 21% to about 27% by weight, wherein at least 99.9% of the feldspar has a particle size less than about 72 microns and the feldspar has a potash to soda ratio of at least 10 to 1;calcined alumina at about 32% to about 38% by weight, wherein at least 99.9% of the calcined alumina has a particle size less than about 44 microns; andclay at about 37% to about 43% by weight, wherein at least 99.9% of the clay has a particle size less than about 22 microns;(B)feldspar at about 28% to about 34% by weight, wherein at least 99.9% of the feldspar has a particle size less than about 72 microns and the feldspar has a potash to soda ratio of at least about 10 to 1;crystalline silica at about 22% to about 28% by weight, wherein at least 99.9% of the crystalline silica has a particle size less than about 44 microns; andclay at about 41% to about 47% by weight, wherein at least 99.9% of the clay has a particle size less than about 22 microns; processing the aqueous composition to form a homogenous mixture; forming the homogenous mixture into a shaped article; and firing the shaped article in a kiln at a temperature of about 2012° F. (1100° C.) to about 2462° F. (1350° C.) to form a friable-resistant dielectric porcelain material.
