Formation of the planar structure of ammonium dihydrogen orthophosphate in porous glass

Resumo

Multiple cycles of porous glass impregnation by aqueous solutions of ammonium dihydrogen orthophosphate with subsequent dehydration lead to gradual accumulation of the salt in the carrier. In the course of progressive filling of the surface of glass in channels with the salt a region with considerably elevated electrical conductivity was found. The correlation between the amount of salt and the specific surface area of glass points to the formation of a continuous planar structure of ammonium dihydrogen orthophosphate in glass pores.
