This thing could conduct spark like metal but its speed would change based on temp or something allowing for timers and contrations instead of using water which can freeze and evaporate you could use this and have a variety of speeds.

1.conducsts to anything that metal can 

2.speed of spark determine by some value like temp or tmp

3.would break at high pressure and turn into broken metal or broken electronics

4.would turn to plasma at <5000 degree we Celsius.

5.would allow protons to discharge the spark like everything else also it will be sparked by electrons

6.will not conduct heat since that will break it.

I think this would be useful since this would allow for many new creations and for old things to get smaller and better
