I am a student and the sandblaster is currently being repaired so i am looking for a solution to this.
Dissolving ceramic with acid.
Ceramic core materials are selectively dissolved from light metal e g.
Examples include the commonly used pharmaceutical antidepressant medication fluoxetine prozac and the material ptfe teflon.
From my experience we needed to dissolve etched alumina on top of aluminum.
It is commonly used to etch glass and silicon.
Hydrofluoric acid is a solution of hydrogen fluoride hf in water solutions of hf are colourless acidic and highly corrosive it is used to make most fluorine containing compounds.
Molten naoh for more multiple material and for more precise stuff i use either 70 hf or the same with adding sulfuric acid and the more cruel and devastating way being molten oxone there are some disadvantages of the last.
The time depended on the.
I need to dissolve ceramic shell from a bronze cast and i was wondering if there is a liquid solution available to remove the remaining shell.
Aluminium or light alloy e g.
A liquid free flowing flux which can dissolve the ceramic is only one part of a successful smelt albeit a big part.
Porcelain one of the stronger ceramics won t really react with any acid except hf hydrofluoric acid as you see in breaking bad.
So we mostly used a mixture of phosphoric acid 6 wt and chromic acid 1 8 wt at 50 o c.
There are many types of ceramics.
