This review evaluates the incorporation of metallic ions into the HAp lattice as a strategic approach to optimize its structural integrity, mechanical performance and biological functionality. Quantitative findings from recent studies show that Ag+ doping at 1 wt% reduces bacterial growth by over 95%, but higher doses ( > 3 wt%) can reduce cell viability by up to 20%. Sr2 + (5 wt%) improves bone regeneration by 25%, though excessive levels may alter lattice stability. Zn2 + at 3 wt% enhances osteoblast proliferation by 60% but can slightly reduce thermal stability. Cu2 + improves angiogenesis and antimicrobial efficacy, but high concentrations can induce cytotoxicity. Furthermore, metallic ion doping enhances the dielectric properties and contributes to anti-cancer capabilities, expanding HAp’s therapeutic potential. The review also highlights advanced applications of metallic ion-doped HAp, including its role in drug delivery systems, implant surface coatings, and even environmental remediation.

This study examines the synthesis and characterisation of hydrosodalite-based geopolymers, which were produced at 150 °C for 2 h in a ventilated oven. In addition, the research investigates the feasibility of enhancing the performance of heat-cured hydrosodalite-based geopolymers by incorporating metakaolin and glass powder into the geopolymer system at weight ratios of up to 40%. XRD analysis indicated that after thermal treatment, the kaolin transformed into a structure containing both residual kaolin and a hydrosodalite phase. FTIR analysis confirmed significant structural changes in the kaolin due to thermal curing. These transformations led to enhanced mechanical strength and water resistance in the samples. Following the hydrosodalite transformation, new endothermic peaks and zeolitic water release that occurred at approximately 200 °C were observed in the samples using DTA-TG analysis. The incorporation of glass powder and metakaolin reduced water absorption and improved water resistance. However, incorporating glass powder did not result in a significant improvement in compressive strength and led to the development of microcracks within the microstructure.
