Calcium (Ca) and silica (Si) ions have attracted intense interest in biomedical applications. The two ions are directly involved in many biological processes; for instance, Ca plays a key role in regulating cellular responses to bioceramics, promoting cell growth, and differentiation into osteoblasts. Si plays a significant role in bone calcification and is helpful for bone density improvement and inhibiting osteoporosis. Calcium silicate ceramics including a large group of trace metal containing calcium silicate‐based compounds are involved in biomedical applications such as repairing hard tissue texture, bone scaffolds, bone cements, or implant coatings. The aim of the study is to provide a comprehensive overview of developments in research on calcium silicate‐based ceramics, such as wollastonite (CaSiO3), diopside (CaMgSi2O6), akermanite (Ca2MgSi2O7), bredigite (Ca7Mg(SiO4)4), merwinite (Ca3MgSi2O8), monticellite (CaMgSiO4), hardystonite (Ca2Zn(Si2O7), and baghdadite (Ca3ZrSi2O9), including degradation, apatite mineralization, and mechanical properties. Finally, the biological in vitro and in vivo presentation for bone tissue repair are summarized, which show promise with regard to application of calcium silicate‐based ceramics as bone repair and replacement materials.

Interesting relationships have been found between refractive index, plasmon energy, electronic polarisability, bond length, microhardness, bulk modulus, force constants and lattice energy. An attempt has been made for the first time to correlate only one physical parameter with others. The calculated values are in good agreement with the experimental values as well as with the values reported in the literature. Refractive index data is the only one parameter required to estimate all the above parameters.
