Application:	Speciation of tin ions in oxide glass containing iron oxide through solvent extraction and inductively coupled plasma atomic emission spectrometry after the decomposition utilizing ascorbic acid.: This study explores the speciation of tin ions in iron oxide-containing glass, utilizing ascorbic acid for decomposition followed by solvent extraction and analysis via inductively coupled plasma atomic emission spectrometry, highlighting a novel analytical chemistry application of hydrofluoric acid (Saijo Y et al., 2022 ). Physicochemical and morphological characterization of a glass ceramic treated with different ceramic primers and post-silanization protocols.: This paper discusses the effects of various ceramic primers and silanization protocols on the physicochemical properties and morphology of glass ceramics, contributing to analytical chemistry by elucidating the interactions and stability of treated surfaces (Moreno MBP et al., 2019 ). Effect of Surface Cleaning Regimen on Glass Ceramic Bond Strength.: Investigates the impact of different surface cleaning regimens, including the use of hydrofluoric acid, on the bond strength of glass ceramics, providing insights into optimal surface treatment methods in material science and analytical chemistry (Lapinska B et al., 2019 ).
General description:	Hydrofluoric acid (HF) is a strong inorganic acid that is commonly used as a source of fluorine for the production of organofluorine compounds and inorganic fluorides. It is also used as a deprotecting reagent in organic synthesis. Additionally, it is also used for breaking strong Si-O bonds to form SiF6− 2 ions in an acidic solution.
