Gram-scale, low-cost, rapid synthesis of highly stable Mg-ACC nanoparticles and their long-term preservation.
A simple chemistry route is reported for the gram-scale, low-cost, rapid synthesis of highly stable Mg-ACC nanoparticles. The possible structure of Mg-ACC can be defined as Mg₀.₁₅Ca₀.₈₅CO₃·H₂O₀.₈₅. The molar ratio of Mg²(+):Ca²(+):CO₃²⁻and the concentrations of the reactants (CaCl₂, Na₂CO₃, and MgCl₂) play important roles in the Mg:Ca molar ratio of the obtained Mg-ACC nanoparticles. In particular, Mg-ACC can be preserved for over one year without crystallization by either storing its dry powder at -5°C or storing it in ethanol at 5°C. The ability to synthesize Mg-ACC nanoparticles on a large scale is useful for biomineralization studies and industrial applications.
