Abstract
A method of fine-tuning the dielectric constant value of an insulating ceramic alloy, and the resulting alloy, and uses thereof, are disclosed. The alloy has the general formula: Mg.sub.x Al.sub.y Ti.sub.z O.sub.4 wherein x+y+z=3 x=1-2 y=0.1-1.9 z=0.1-0.9 and is preferably made from 10 to 90 mol percent of magnesium titanate and 90 to 10 mol percent of magnesium aluminate. The mole ratio of the titanate to the aluminate in the alloy is varied in order to vary the value of the dielectric constant of the alloy. The alloy has a density which is at least 98% of the theoretical density of the alloy, and a dielectric constant of 8.5 to 13.8. The alloy can be used in applications wherein dielectric materials have previously been utilized, such as a substrate for an electrical circuit.
