the problem with teflon is it does not stick to anything very well and it requires a bonding agent. its this agent you need to inspect.
tungsten disulphid may be an alternative. it can take the head better than the teflon and does not require a bonding agent. also an inert material so your safe...
Water has the highest thermal capacity without getting into exotic materials. Black carbon will trap the IR energy the best. Copper is a great thermal conductor. I would suggest a flat water filled copper tank coated with black carbon.
You can have the black carbon impinged into the copper. Use...
thanks for the tips to both...
I know I was ok with the vapor issue, just trying to be as optimal as possible. (maybe too picky) Energy consumption is going to be an issue with heating the ovens and the duration of vacuum pumping. This will be a mobile lab and will be running off batteries...
I used to manage a scrap yard and my advice is to desolder with acetaline torch. Then while still hot enough to keep the solder wet, drop them on concrete floor. Jusr be carefull of the solder splatter... You will not hurt the nickle.
I am looking for the thermal conductivity values for 304 and 316 ss. Google was no help. Also need to know which meterial is more resistant to absorbing water vapor. This will be used in a vacuum oven up to 29 in/HG.
