Abstract
Disclosed herein are embodiments of materials having high thermal conductivity along with a high dielectric constants. In some embodiments, a two phase composite ceramic material can be formed having a contiguous aluminum oxide phase with a secondary phase embedded within the continuous phase. Example secondary phases include calcium titanate, strontium titanate, or titanium dioxide.
Claims20
A dual-phase composite ceramic material, the material comprising:
- a primary phase;
- and
- at least one secondary phase located within the primary phase forming a dual-phase composite, the dual-phase composite having a dielectric constant of greater than 20 and a thermal conductivity of greater than 20 W·m−1·K−1.
A method of forming a dual-phase composite ceramic material, the method comprising:
- mixing together at least two materials that will form out a primary phase and a secondary non-contiguous phase, the materials forming the primary phase being generally non-reactive with materials forming the secondary phase;
- and
- sintering the materials to form a composite ceramic having the primary generally contiguous phase and the secondary non-contiguous phase, the composite ceramic having a dielectric constant of greater than 20 and a thermal conductivity of greater than 20 W·m−1·K−1.
A radiofrequency component formed from a ceramic material comprising:
- a primary phase;
- and
- at least one secondary phase located within the primary phase forming a dual-phase composite, the dual-phase composite having a dielectric constant of greater than 20 and a thermal conductivity of greater than 20 W·m−1·K−1.
