Diopside ( C a M g S i 2 O 6 ) ceramics was synthesized and fabricated by a simple solid‐state reaction rather than other used processes. This new and economic approach for diopside fabrication consists mainly of replacing the usually used starting materials by other more economic (activated C a O · M g O powders), using conventional sintering and microwave sintering. The P 2 O 5 addition (0.5–5.0 wt%) promotes sintering, crystallization, and bioactivity. Additionally, a considerably low weight loss ratio (0.21%) was also obtained for these samples, after 2 days of soaking in lactic acid. Carbonated hydroxyapatite ( CHA ) formation in simulated body fluid was confirmed for all sintered samples. Both sintering and CHA formation mechanisms were proposed.
