Abstract
Analcime has been synthesized from natural rhyolitic tuff and green tuff (Miocene age) at 200° C and 20 kg/cm2 with solution of Na2SiO3 (12%) in 50- to 260-hr runs. From the diffraction intensities, it was found that the alteration products of green tuff contained more analcime than those of rhyolitic tuff. It has been concluded that the lithological character of starting materials and the chemical behavior of reaction products are important controlling factors in analcimization.
