kleinwolf Posted September 18, 2009 Share Posted September 18, 2009 Does anyone know an easy way to make cristal grow, by dilution of a chemical compound in a liquid ? And maybe too, if there is a list to which form of the cristal corresponds to which powder ? Link to comment Share on other sites More sharing options...
CaptainPanic Posted September 18, 2009 Share Posted September 18, 2009 Crystal growth by dilution? Usually you want to concentrate a chemical compound to cause crystallization. I've never heard of a liquid-liquid demixing with the liquid then immediately crystallizing. Link to comment Share on other sites More sharing options...
McCrunchy Posted September 18, 2009 Share Posted September 18, 2009 It isn't exactly dilution, but you can add ethanol or acetone to a concentrated aqueuous solution of a salt to make it precipitate. Ethanol is miscible with water, but the salt's solubility decreases dramatically in the mixture. To get a list of lattice structures/growth habits for different minerals and powders, the best site I can recommend is : http://webmineral.com/ McCrunchy 3 Link to comment Share on other sites More sharing options...
