I am pretty quickly putting together the pieces to do a simple replication. I would like the feedback from this forum on roadblocks, dangers, suggestions.
- Multiple quartz/silica tubes with in ID of 2 mm, OD or 5 mm.
2 tubes are filled with pure nickel (3 micron power).
2 tubes are filled with a mix of TiH3 (titanium Hydride) and Ni 3 microns.
The tubes are sealed with a high temperature (2000 F maximum temperature).
The heating is done by direct joule heating of the power by providing direct current with two electrodes reaching across the seal. (think arc furnace).
The tubes can run in parallel and share the power source.
The temperature is measured with 3 cmos monochrome cameras with 3 bandpass filters to fit a black body.
The entire setup is in a polycarbonate enclosure.
So questions for the group:
Did anybody consider microwave heating ? simple and consistent for differential tests.
Any opinion on the need for Lithium ? I do plan for the simplest initial test with just the Ni + H
Would the demonstration of a reproducible higher temperature for the Ni + H compared to pure Ni be a meaningful test?
How long does a test really has to last?
Does vacuum or other neutral gas purging needed?
