General description
Semiconductor grade hydrochloric acid has been characterized by inductively couple plasma mass spectrometry (ICP-MS). The trace detection of V, Cr, As and Se in 20% HCl was determined in the study. It′s efficiency as a microabrasive was studied.
Application
Hydrochloric acid may be used in the formulation of “standard cleaning bath” to purify metallurgical grade silicon (MGS) and polysilicon. Varying concentrations of the acid aided formation of spherical and rod like cellulose nanocrystals. Aqueous mixture of hydrochloric acid and Α-hydroxy acids (lactic, citric, malic, and tartaric acids) may be used to etch a III-V semiconductor (InP).
