A STUDY OF LITHIUM FLUORIDE ETCH MORPHOLOGIES USING SILICA GEL.

Abstract

Cleavage surfaces of lithium fluoride were etched on a silica hydrogel containing ferric ions as inhibitor. The dissolution etch pits and features were examined by interference and electron microscopy. The ledge structure of pits thus formed is very regular. It is proposed that the gel eliminates turbulence in the system and retards the diffusion of ferric ions towards the dissolving interface. An explanation for the observed rounding of pits at very high inhibitor concentration is proposed. (Author)
