![]() ![]() Native layers of xonotlite have a very smooth morphology, while after calcination, the appearance of small cracks in the coating can be observed but the adhesion strength of the coatings to the substrate is improved. Stable suspension of the material was obtained using isopropanol containing 1 % water as dispersing medium and Ca-nitrate as a charging additive. Optimal conditions for electrophoretic deposition of xonotlite on 304-type stainless steel have been achieved by appropriate selection of electric field strengths, dispersing medium, and dispersants. SEM observation of xonotlite morphology revealed tiny needle-like crystals joined together forming dendritic or globular aggregates. Crystallite size and lattice strain of all crystal phases were calculated using Scherrer and Williamson-Hall method. it supports tabs, more commands, command completition, scrollbar, backdrops and so on. Calcination of the obtained sample at 900 ˚C has resulted in a complete transformation of xonotlite to wollastonite which was detected as only a crystal phase. Detailed structural characterization by using the XRD technique revealed that the obtained material contains a small quantity of wollastonite (up to 3 %) as an impurity. In this research, xonotlite was synthesized by a hydrothermal method in the Si-Ca-Na-H 2O system.
