What is the reaction of Ethyl 2-cyanoacrylate (superglue) and Alumina powder?

[Qmavam]

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.

released smoky fume

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.
