Abstract: A low K value, high Q value, low firing dielectric material and method of forming a fired dielectric material. The dielectric material can be fired below 950° C. or below 1100° C., has a K value of less than about 8 at 10-30 GHz and a Q value of greater than 500 or greater than 1000 at 10-30 GHz. The dielectric material includes, before firing a solids portion including 10-95 wt % or 10-99 wt % silica powder and 5-90 wt % or 1-90 wt % glass component. The glass component includes 50-90 mole % SiO2, 5-35 mole % or 0.1-35 mole % B2O3, 0.1-10 mole % or 0.1-25 mole % Al2O3, 0.1-10 mole % K2O, 0.1-10 mole % Na2O, 0.1-20 mole % Li2O, 0.1-30 mole % F. The total amount of Li2O+Na2O+K2O is 0.1-30 mole % of the glass component. The silica powder can be amorphous or crystalline.
