Application of Track Membranes to Fabricate Potassium Dihydrogen Phosphate Microstructures

Abstract

A method to fabricate insulator microstructures from aqueous solutions using track membranes as a template has been developed by an example of potassium dihydrogen phosphate. It is shown that microstructures are formed in pores of a track membrane under conditions of forced flow of supersaturated crystallization solution through this membrane. These microstructures continue to grow beyond the pore volume, mainly on the membrane side facing the flow. Their transverse sizes and growth direction are determined by the direction and diameter of membrane pores.
