This paper seeks to provide an extensive review of the ferroelectric material, potassium dihydrogen phosphate (KDP) including its properties, synthesis techniques, and activities up to the year 2022. KDP has attracted much attention in the ferroelectric materials because of its outstanding electro-optic and nonlinear optic performance. In this paper, discussion on the crystal structure and the ferroelectric behaviours and the temperature of KDP has been given in details. Some synthesis approaches and characterization techniques are described and current developments in the field of the KDP crystal are also perspective. The review also examines the merits, limitations and feasibility of the KDP in various fields including laser systems, electro-optical modulators and frequency converters. Last but not the least; they have put forward the future research directions to consolidate the knowledge and use of this highly ferroelectric material.
