Nepheline Syenite Decomposition Using NaOH by Hydrothermal Reaction
《矿物学报》2013年第S1期137-137,共1页ZHANG Pan MA Hongwen YANG Jing MA Xi SU Shuangqing 
Project supported by National Key Technologies Research and Development Program for 11th Five-year Plan (No. 2006 BAD10B04);China Geological Survey Project (No. 12120113087700)
Nepheline syenite is an important potassium-rich rock resource. Nepheline syenite powder was decomposed successfully by hydrothermal reaction using NaOH additive. Hydroxycancrinite (Na8(Al6Si6O24)(OH)2·2H2O ) solid a...
