Abstract
Novel molecular sieves are disclosed which are oxides of (a) an alkali metal, an alkaline earth metal and/or ammonium, (b) beryllium, cobalt and/or zinc, and (c) phosphorous, arsenic and/or vanadium, and optionally contain water. These zeolite-like materials, which contain little or no aluminum or silicon, can be made by a novel low temperature process. The molecular sieves are useful as ion exchange resins.
