Title:
METHOD FOR GROWING CRYSTALS IN DOMESTIC CONDITIONS
Document Type and Number:
WIPO Patent Application WO/1999/049109
Kind Code:
A1
Abstract:
The present invention pertains to the field of crystallography and may be used for growing monocrystals as well as crystal junctions in domestic conditions and for decorative purposes. The purpose of this invention is to provide a technique for creating monocrystals or crystals junctions having decorative shapes. To this end, this invention comprises preparing an aqueous solution of a base substance, such as vitriol blue CuSO¿4?*5H¿2?O or a blood-red salt K?3¿[Fe(CN¿6?)], until a saturated solution is obtained, said solution being then heated at a temperature of up to 45°. An unsaturated solution is then obtained and a crystal seed previously grown on a frame with a weight and a loop is added thereto at a temperature of (T¿room? + 8°). It is thus possible to grow large-size crystals having predetermined dimensions and decorative shapes. Apart from those mentioned above, the base solutions may consist in aqueous solutions of mineral salts such as nickel vitriol NiSO¿4?*7H¿2?O, magnesium sulphate MgSO¿4?*7H¿2?O, potassium dichromate K¿2?Cr¿2?O¿7?, a yellow blood-red salt K¿4?[Fe(CN)¿6?]*3H¿2?O, manganese dichloride MnCl¿2?*4H¿2?O, copper dichloride CuCl¿2?*2H¿2?O, etc.
