Note: Heating magnetic iron oxide in water (hyperthermia)
Objective:
Heating magnetic iron oxide (Fe2O3) in water for hyperthermia application to determine the curve of temperature vs. time during induction heating
End Product:
Fe2O3 in water solution
Equipment:
Ambrell 2 kW induction heating system, equipped with a remote workhead containing two 0.33 μF capacitors for a total of 0.66 μF
An induction heating coil designed and developed specifically for this application
Materials:
Magnetic iron oxide in water (magnetic field is 50-200 kHz, 30 kA/m), glass vial
Temperature:
Varies
Frequency:
344 kHz
Testing:
A two turn helical coil is used to heat the glass vial. The temperature vs. time results are:
âÂË 66 - 107 °F (19 - 42 °C) in 10 seconds
âÂË 66 - 145 °F (19 - 63 °C) in 20 seconds
âÂË 66 - 170 °F (19 - 77 °C) in 30 seconds
Benefits:
-
Rapid & localized heating
-
Uniform controllable heat
-
Small bench top footprint
-
Even distribution of heating
