摘要： Various embodiments of the invention include systems and methods of generating nano-sized salt particles. These methods include generation of a supersaturated solution of a salt MX by mixing of salts MY and NX in which the solubility of MX is lower than that of MY, NX or NY. In some embodiments, nano-sized particles of MX are grown further by further adiabatic addition of salts MY and/or NX. In some embodiments, MX includes potassium nitrate. Some embodiments include compositions of MX configured for use in treatment of dentine sensitivity.

摘要： PROCESS FOR MAKING KNO3 FROM KCL AND CA(NO3)2 SALTS, THESE SALTS BEING REACTED IN THE PRESENCE OF A RECYCLE SOLUTION TO FORM SOLID KNO3, THE RECYCLE SOLUTION CONTAINING CA+, K+, NO3-, AND CL- IONS, SEPARATING THE SOLID KNO3 AT A TEMPERATURE FROM ABOUT -10 TO +20* C., AND TREATING THE MOTHER LIQUOR FROM WHICH THE KNO3 HAS BEEN PRECIPITATED WITH LIME TO THEREBY PRECIPITATE CALCIUM OXYCHLORIDE, CACL2$3CAO$16H2O, TO THEREBY REDUCE THE CALCIUM CHLORID CONTENT OF THE MOTHER LIQUOR. IMPROVEMENT COMPRISES EFFECTING THE PRECIPITATION OF CALCIUM OXYCHLORIDE IN THE PRESENCE OF A SOLID PHASE MADE UP SUBSTANTILLY OF CALCIUM OXYCHLORIDE AND NOT MORE THAN 5% BY WEIGHT OF FREE LIME AT A TEMPERATURE THAT IS FROM FROM ABOUT 5 TO 15* HIGHER THAN THE TEMPERATURE OF SEPARATION OF THE KNO3, AND MAINTAINING THE CONCENTRATION OF CHLORIDE IONS OF THE LIQUID PHASE WITHIN $5 GRAMS PER LITER OF THE SATURATION CONCENTRATION.
