Ferroelectric Magnesium Hydrogen Phosphate MgHPO 4 (MHP) single crystals are grown by slow diffusion of magnesium chloride in sodium metasilicate gels impregnated with orthophosphoric acid. Bright and transparent prismatic, tabular, and isometric habit MHP crystals upto 3 × 2 × 1 mm 3 are obtained. Results of chemical, X‐ray diffraction, EDAX, microhardness and magnetic analysis are reported. The average etch pit density is determined by chemical etching to be 7 × 10 3 cm −2 . Microtopographic investigations revealed the mechanism of crystal growth.
