AI Thread Summary
The discussion centers on experimenting with superglue and alumina powder for repairs. A user noted that mixing these two substances resulted in an exothermic reaction that produced smoky fumes, prompting a quick relocation outdoors. The user aims to create a thermally conductive molded shape and questions the effectiveness of using superglue alone without baking soda for repairs. Concerns were raised about the safety of mixing random chemicals, with suggestions that the reaction may be due to catalytic actions from dry alumina powder. Comparisons were made to other chemical reactions, such as the reaction between dry calcium hydroxide and glycerine, which also generates heat and solidifies.

After using Superglue and baking soda for repairs, and seeing cement, ashes and other mixes, I wondered what happens with superglue and alumina powder. I mixed the two and it is more exothermic and released smoky fumes, to the point where I quickly moved it outside. I have yet to check my result, but thought it might be good to see what I have. My hope is to make something thermally conductive formed in a molded shape.

Try your repairs using just superglue, and no baking soda. Does it still glue things together?
I honestly cant see why you used sodium bicarbonate, not why you played with aluminium powder.

Which is a good reason not to mix together random chemicals.
 
It's possibly due to some catalytic action, but it's hard to say.
 
was it extremely dry alumina powder? then that was setting the super glue, the same thing happens if u add really dry calcium hydroxide to glycerine, it goes really hot and solidifies.

Thread 'How to make Sodium Chlorate by Electrolysis of salt water?'

I have a power supply for electrolysis of salt water brine, variable 3v to 6v up to 30 amps. Cathode is stainless steel, anode is carbon rods. Carbon rod surface area 42" sq. the Stainless steel cathode should be 21" sq. Salt is pure 100% salt dissolved into distilled water. I have been making saturated salt wrong. Today I learn saturated salt is, dissolve pure salt into 150°f water cool to 100°f pour into the 2 gallon brine tank. I find conflicting information about brine tank...
