| titleOfInvention | A method for etching a solid containing aluminum ions |
| abstract | A method of etching a solid in waterninsoluble, containing aluminum ions,nby a process which avoids the formation of insolublenpollutants adhering to the surfacensubstances that can be easily cleanednsurfaces, with the choice of temperature and concentrationnetching solution can be achieved eithernhigh chemical purity and / or opticalnan etched surface permeability, suitable for examplenfor cleaning products from single crystalsncorundum or phosphate photoluminescentnglass by etching the surface inna solution prepared from 60 to 99% by weight of the acidnphosphorous H3PO4 and / or sulfuric H28O4nand 1 to 40 hipot. % of water with such additionnboron and lithium compounds to keep in solutionnduring etching, the mass ratio of ions wasnaluminum, boron and lithiumnAl3 +: B3 + 3 and Al3 +: Li112,npossibly without this formulation when the compositionnthe etched material corresponds to the abovenweight ratio of aluminum, boron ionsnand lithium. |
