Dissolving Ceramic With Acid

Stronger acids such as fluoroantimonic acid might be able to dissolv.

Dissolving ceramic with acid.

From my experience we needed to dissolve etched alumina on top of aluminum. Aluminium or light alloy e g. 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. Porcelain one of the stronger ceramics won t really react with any acid except hf hydrofluoric acid as you see in breaking bad.

Aluminium alloy castings which are themselves susceptible to attack by caustic alkali solutions by providing the core material with a substance containing hydrogen donor group which is capable of producing nascent hydrogen and contacting the core with fused anhydrous caustic alkalis. Examples include the commonly used pharmaceutical antidepressant medication fluoxetine prozac and the material ptfe teflon. Elemental fluorine is produced from it. It is commonly used to etch glass and silicon.

The time depended on the. Ceramic core materials are selectively dissolved from light metal e g. So we mostly used a mixture of phosphoric acid 6 wt and chromic acid 1 8 wt at 50 o c. 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.

I am a student and the sandblaster is currently being repaired so i am looking for a solution to this.
