Patent ID: 7220365

Claim:
A heat transfer element consisting essentially of a high heat transfer medium, wherein the high heat transfer medium is formed by dissolving the following compounds in water to produce a mixture, and drying the resulting mixture to produce said heat transfer medium product with said compounds in the following weight percentages: (1) Cobaltic Oxide (Co2O3), 0.5–1.0%; (2) Boron Oxide (B2O3), 1.0–2.0%; (3) Calcium Dichromate (CaCr2O7), 1.0–2.0%; (4) Magnesium Dichromate (MgCr2O7.6H2O), 10.0–20.0%; (5) Potassium Dichromate (K2Cr2O7), 40.0–80.0%; (6) Sodium Dichromate (Na2Cr2O7), 10.0–20.0%; (7) Beryllium Oxide (BeO), 0.05–0.10%; (8) Titanium Diboride (TiB2), 0.5–1.0%; (9) Potassium Peroxide (K2O2), 0.05–0.10%; (10) A selected metal or Ammonium Dichromate (MCr2O7), 5.0–10.0%; where “M” is selected from the group consisting of potassium, sodium, silver, and ammonium; (11) Strontium Chromate (SrCrO4), 0.5–1.0%; and (12) Silver Dichromate (Ag2Cr2O7), 0.5%–1.0%, the heat transfer medium is positioned on a substrate.
