Abstract

This study was carried out to investigate the effect of a complete exchange of Ca with Zn ions on the structure of brushite (CaHPO·2HO), which might be advantageous in the production process of CaZnHPO·nHO. To acquire the starting solutions needed for the current study, (NH)HPO, Ca(NO)·4HO, and Zn(NO)·6HO were utilized in several molar concentrations. The findings indicate that Ca is partly substituted by Zn when the Zn/Ca molar ratio is below 0.25 and that Zn doping hinders the crystallization of brushite. A continued increase in the Zn/Ca molar ratio to 1 (at which point the supersaturation of the Zn solution rises) led to a biphasic compound of monoclinic brushite and parascholzite precipitate. Elevating the Zn/Ca molar ratio to 1.5 resulted in a precipitate of a parascholzite-like mineral. Finally, increasing the Zn/Ca molar ratio to 4 and above resulted in the formation of the hopeite mineral. Future biomaterial production with specific and bespoke characteristics can be achieved by adjusting the Zn/Ca ratio in the starting solution. It Rhas been established that the Zn/Ca ratio in the starting solution can be adjusted to obtain minerals with specific compositions. Thus, new synthesis methods for parascholzite and hopeite were introduced for the first time in this manuscript.

摘要

本研究旨在探究用锌离子完全置换钙对透钙磷石（CaHPO₄·2H₂O）结构的影响，这在CaZnHPO₄·nH₂O的生产过程中可能具有优势。为获得本研究所需的起始溶液，使用了不同摩尔浓度的(NH₄)₂HPO₄、Ca(NO₃)₂·4H₂O和Zn(NO₃)₂·6H₂O。研究结果表明，当锌/钙摩尔比低于0.25时，钙部分被锌取代，且锌掺杂会阻碍透钙磷石的结晶。锌/钙摩尔比持续增加至1（此时锌溶液的过饱和度升高）会导致单斜透钙磷石和磷锌矿沉淀的双相化合物。将锌/钙摩尔比提高到1.5会导致类似磷锌矿的矿物沉淀。最后，将锌/钙摩尔比提高到4及以上会导致磷锌矿矿物的形成。通过调整起始溶液中的锌/钙比，可以实现具有特定定制特性的未来生物材料生产。已经确定，可以调整起始溶液中的锌/钙比以获得具有特定组成的矿物。因此，本手稿首次引入了磷锌矿和磷锌矿的新合成方法。
