Calcium phosphate (CaP)-based bioceramics are widely used in orthopedics and dentistry for bone regeneration due to their good biocompatibility, osseointegration and osteoconduction. Synthetic hydroxyapatite (HAp) is the most widely used bioceramic coating in biomedical implants as it has a chemical composition similar to that of the bone. The properties of the coating depend on the nature of powders and in turn on the source of the powders. Hydroxyapatite powders can be prepared by a variety of chemical routes like co-precipitation, hydrothermal, sol-gel, solution combustion, etc. Among these methods, the solution combustion method is promising as it is a single step, cost-effective and energy-efficient process and yields high purity ceramic powders compared to conventional multi-step wet chemical processes. This method can also yield powders in nano and micron size range and can be used for the fabrication of coatings using methods like plasma spraying, suspension plasma spraying, electrophoretic deposition, etc. This chapter gives an overview of the solution combustion synthesis of pure and doped hydroxyapatite powders and their characterization. The last section of this chapter discusses the solution combustion synthesis of plasma sprayable hydroxyapatite powder, fabrication of HAp coating and characterization of the developed plasma-sprayed coating.
