“…A submicrometer/nanocrystalline HA coating was made from inexpensive liquid precursors. 7 Using an organic sol-gel solution of calcium nitrate tetrahydrate and triethyl phosphate, porous HA coatings were formed on a Ti-6Al-4V substrate. 6 The coating exhibited microstructural features typically found in solution precursor plasma spray processes; a combination of melted and unmelted deposits and small hollow spheres.…”

Solution precursor plasma spray (SPPS) synthesis is a simple, single-step, and rapid technique for synthesizing nano-ceramic materials from solution precursors. This innovative method uses molecularly mixed precursors as liquids, avoiding a separate processing method for the preparation of powders and enabling the synthesis of a wide range of metal oxide powders and coatings. Also, this technique is considered to be promising for the formation of nonequilibrium phases in multi-component oxide systems. This short review provides an insight into the important aspects of SPPS, the properties obtained in comparison to conventional plasma spray, and the potential applications of the SPPS process. S.
