Therefore, the biocompatibility of Si-HA seems to be good and it is a feasible material as bone substitute.
Materials and Methods Preparation of 2wt% Si-substituted Hydroxyapatite The 2wt% Si-substituted hydroxyapatite (Si-HA) was prepared using a precipitation method.
Based on these results, the 2wt% Si-substituted hydroxyapatite has good biocompatibility and seems to be an useful material for implants and bone substitutes.

It is represented with -3σ, b, a, or s basis of material performance according to mechanical properties data representation standards.
However, it is difficult to precisely characterize the product cushioning suitability, for these methods are value design methods and ignore environmental conditions, material properties, cushion geometric parameters, the stochastic nature of the fragility and other design parameters.

On the other hand, release of P from production and life of human being is one of the primary nutrients which leads to eutrophication and threatens the dwindling water resources .In order to reduce the negative effects of overloading the ecosystems with P, it is necessary to investigate various techniques and materials that could contribute to the removal as well as recycling of P.
In Fig.1b, the well dispersed white materials were magnesium oxide ,as an active component MgO played an important role in the process of adsorption.
