'''稀土分子筛'''，又称稀土分子筛(molecular sieve type rare earths) M2/nO·Al2O3·WSiO2·YH2O 淡黄色粉末。溶于强酸和强碱。
又称稀土分子筛(molecular sieve type rare earths) M2/nO·Al2O3·WSiO2·YH2O 淡黄色粉末。溶于强酸和强碱。不溶于水和有机溶剂。活性高。选择性好。焦化倾向小。由水玻璃、偏铝酸钠、氢氧化钠按一定摩尔比混合后，在搅拌下加入稀硫酸，然后加入定向剂，经结晶，过滤，洗涤，加入稀土元素的氯化物进行离子交换(交换率70%)，洗涤(至无氯离子)，干燥，加入硅溶胶捏合造粒，灼烧活化制得。主要用于石油催化裂化反应催化剂。<ref>[https://www.sohu.com/a/357235440_120239551 稀土在各领域的作用 ]搜狐</ref>
