Sythesis of Ultranarine from The Shirasu and Zeolites.

Shirasu被广泛分布，作为在Southenrn部分的火山升级上累积。我们调查了Shirasu、Na-P型沸石中的Ultramarine合成和在100-120 ℃过滤Na-P的羟基晶体，C.通过受控碱性条件下的羟基治疗，Shirasu早期转化为羟基和Na-P型沸石。随着氯化钠的增加，苏打水也随之增加。索达利特人（3Na_2O·3Al_2O_3·6SiO_2·2NaCl）， hydroxysodalite（3Na_2O·3Al_2O_3·6SiO_2·2H_2O） and Ultramarine（3Na_2O·3Al_2O_3·6SiO_2·NaS_3）有相同的框架，因此， Shirasu被处理为各种硫酸盐（S，Na_2S，Na_2SO_4， Na_2S_2O_3）在120个C下的各种碱性条件下，用于将硫酸盐插入苏打框架。（S. S）将硫酸盐类似物包含从Shirasu、Na-P型沸石和P-过滤器，包括各种硫酸盐。但是，当一个大的硫磺（S，Na_2S）被添加时， Natrodavyne（3Na_2O·3Al_2O_3·6SiO_2·Na_2CO_3）在1250 μ C中捕获了蓝色-、红色-、黄色-和白色-Ultramarine，当在2-4分钟内捕获了各种不同类型的苏打框架S. S的硫酸。从Shirasu衍生出的S. S比Na-P型沸石更鲜艳，当计算颜色时，P-过滤。It was understanded that sulfur were contained 7.8%in S. S derived from Shirasu （8.6%in case of Ultramarine）。

Shirasu are widely distributed as accumulation of volcanic eruption over Southenrn part of Kyushu. We investigated on synthesis of Ultramarine from Shirasu, Na-P type zeolite and filtrate of Na-P by hydrothermal treament at 100-120ﾟC.By hydrothermal treatment under controled alkarine condition, the Shirasu was early transformed to hydroxysodalite and Na-P type zeolite. As the addition of NaCl was increased, sodalite was obtained. The sodalite (3Na_2O・3Al_2O_3・6SiO_2・2NaCl), hydroxysodalite (3Na_2O・3Al_2O_3・6SiO_2・2H_2O) and Ultramarine (3Na_2O・3Al_2O_3・6SiO_2・NaS_3) have a same framework.Therefore, Shirasu was treatmented with various Sulfurs (S,Na_2S,Na_2SO_4, Na_2S_2O_3) under various alkarine condition at 120ﾟC for insertion of Sulfur into sodalite framework.The sodalites framework (S.S) containing Sulfur similar to Ultramarine were derived from Shirasu, Na-P type zeolite and P-filtrate with various Sulfurs. But, when a large amount of sulfur (S,Na_2S) was added, Natrodavyne (3Na_2O・3Al_2O_3・6SiO_2・Na_2CO_3) was obtained.Blue-, red-, yellow-and white-Ultramarine were obtained when were calcinated various kind of sodalite framework S.S containing sulfur for 2-4 minute at 1250ﾟC.In conclusion, the S.S derived from Shirasu were more colorful than Na-P type zeolite and P-filtrate when calcinated for coloring. It was understanded that sulfur were contained 7.8% in S.S derived from Shirasu (8.6% in case of Ultramarine).
