| titleOfInvention | Process for preparing potassium silicate solutions |
| abstract | PCT No. PCT/EP90/01948 Sec. 371 Date May 26, 1992 Sec. 102(e) Date May 26, 1992 PCT Filed Nov. 14, 1990 PCT Pub. No. WO91/08170 PCT Pub. Date Jun. 13, 1991.A process is disclosed for the hydrothermal production of potassium silicate solutions with high SiO2:K2O molar ratios, by the hydrothermal reaction of quartz sand with aqueous potassium hydroxide solutions at temperatures in the range of 150 DEG to 300 DEG C. at the pressures of saturated water vapor corresponding to these temperatures in a pressure reactor, which is characterized in that the potassium silicate solutions obtained thereby, which have SiO2:K2O molar ratios of less than 2.75:1, are then reacted with a quartz tempered at temperatures in the range of over 1100 DEG C. up to melting point, the temperatures and pressures also being maintained in the ranges named. |
