My idea is to slowly oxidize the aluminium chips in a mixture of water, ethanoic acid, potassium aluminium sulfate (copper dust catalyzed) with help of atmospheric air. What would be the required binder? how to remove ionic impurities upon satisfactory combustion? can it be cured or fired to temperature below 500 degree celsius?
the refractory is planned to take no structural load, just carry organic-inorganic chemical mixtures that would be pyrolyzed and inorganic salt leached from its ash. pyrolysis temperature is below 400 celsius. the ash can contain alkali and phosphate.
This question is rooted from my observation that Al chips generated from interior design (door, window frame) are not recycled or sent back to manufacturers but rather dumped whimsically.
I am not sure, that this idea economically relevant. I recommend to begin with patent searçh.
Hello. It's not entirely clear - do you want to get refractory material from aluminum chips? If the operating temperature of the material is below 400 degrees, why do you call it refractory? Is the technology that you offer too expensive? Why not get acid emphasis on traditional ceramic technology?
