  • Process for the production of very fine-particle zeolitic alkali metal aluminum silicates
    Patent number: 5645811
    Abstract: Finely ground zeolithic alkali metal aluminum silicates having the general formula: xMe.sub.2 O.Al.sub.2 O.sub.3.ySiO.sub.2.zH.sub.2 O, are prepared by mixing both reaction components, alkali metal silicate and alkali metal aluminate, in the presence of a stoichiometrically excessive amount of alkali metal hydroxide. The thus obtained gel is matured, the reaction mixture is heated up to crystallisation temperature, then crystallised. During crystallisation, at least one of both reaction components is added to the reaction mixture.

  • Stabilized zeolite A suspensions
    Patent number: 4529541
    Abstract: Stabilized aqueous zeolite A suspensions containing a nonionic surfactant as a stabilizer and an anionic surfactant as a stabilizer auxiliary are improved by using at least one sulfated C.sub.10-20 alcohol or substituted alcohol as the stabilizer auxiliary. In a further embodiment, an acid salt may be added to the suspension to adjust the pH to below 12.
