Description General description Tris(tert-butoxy)silanol can react with various metal alkyl amides to act as precursors for vapor deposition metal silicates. It also acts as a suitable precursor for deposition of silica. Application Tris(tert-alkoxy)silanols reacts with tetrakis(dimethylamino)-hafnium vapor(Hf(N(CH3)2)4) for vapor phase deposition of hafnium silicate glass films. Tris(tert-butoxy)silanol is used for atomic layer deposition (ALD) of highly conformal layers of amorphous silicon dioxide and aluminum oxide nanolaminates. Packaging 5, 25 g in glass bottle
