摘要:
The present disclosure discloses an ion conductor with high room-temperature ionic conductivity and a preparation method thereof. This method employs solid-phase sintering and ion exchange technologies, and can prepare crystalline and amorphous transition metal silicate by adjusting the addition ratio of sodium source. The chemical formula of the prepared transition metal silicate is A2-2xMSiO4-x, wherein A is Na, Li, Mg, Ca, or Zn; M is a transition metal Fe, Cr, Mn, Co, V, or Ni, when 0

Storage-stable, pourable and pumpable silicate suspensions are prepared by wet milling of aluminosilicates, after the preparation of the latter, without intermediate drying.
摘要:
High purity synthetic zeolites having open frameworks, such as offretite, uncontaminated with detectable traces of other zeolites, can be synthesized by the hydrothermal reaction of a silica source, alumina source, sodium hydroxide and/or potassium hydroxide in the presence of a zeolite nucleation slurry synthesized from a mixture of a silica source, alumina source, sodium hydroxide and/or potassium hydroxide and an organic template agent. The preferred organic template agents are the quaternary compounds wherein the central element is one from Group 5A of the Periodic Table and various conjugated aromatic compounds. The zeolite synthesis mixture itself does not contain any organic ion template agent. With this organic template agent not being required, the nucleation slurry is used to promote crystallization of the synthesis mixture to the open framework type of zeolite.
