How to Heat Treat Catalyst Packs with
Samarium Nitrate

This Catalyst pack process was given to me by James McCormick back it the early seventy's. I used this process to make my catalyst packs from 1971 to 1980 for rocket cars and other vehicles that I built for myself and my customers. My cars continued to run with with the same catalyst packs until the supply of 90% Hydrogen Peroxide dried up.

CATALYST SCREEN TREATMENT FOR 90%
HYDROGEN PEROXIDE ROCKET MOTORS

Treat the (10) 40 mesh screens and (60) mesh screens as follows:

A. Apply silver plating to the nickel wire screens with a modular (rough) finish to a thickness of .001 to .002. The Plating process must be one, which will survive the heat generated in the motor. Plating processes developed for constructing fuel cells will work. This involves application of an intermediate coating (copper) to improve the silver-nickel bond.

B. The plated screens, then have to be treated as follows:

EQUIPMENT:
  • Clean oven at 850-900 degrees Fahrenheit.
  • Stainless steel racks or trays to hold screens in oven.
  • Stainless steel trays to hold solutions.
  • 10% by weight samarium nitrate solution.
  • Nitric acid, about 10% concentration.

1. Dip screens in nitric acid to remove organic impurities.
2. After cleaning screens, handle only with clean gloves or tongs.
3. Rinse thoroughly is distilled water.
4. Heat screens to 850-900 degrees in oven.
5. Immerse screens in samarium nitrate solution while still hot.
6. Return in oven, heat for 30 minutes after oven reaches 850-900 degrees.
7. Repeat steps 5 and 6 and minimum of 4 times.
8. A dull straw color indicates coating is applied properly and should be uniform over the screens.

C. Keep the screens stored in a clean container until ready to install in the motor or gas generator. Handle with gloves, do not allow foreign matter to drop into the pack during assembly. Take care so that pipe sealant, Teflon tape, lubricants, etc., do not pass downstream into the catalyst pack.
