1. 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.
