Recently, strontium carbonate (SrCO3) and barium carbonate
(BaCO3) have been found to be very important materials for
ceramic industries [1–4]. SrCO3 is a reagent for the production
of color television glass tubes and ferrite magnets for DC motors.
It is widely used in the production of iridescent glasses, pigments,driers, paints, fireworks and pyrotechnics. BaCO3 has a more thermodynamically stable crystal modification among the heavy metal carbonates. It has attracted attention due to its close relationship with aragonite and applications in many ceramic and glass industries. It is also highly utilized precursors for the synthesis of magnetic ferrites and ferroelectric materials. Related biomimetic approaches for BaCO3 crystallization include influence of urease, presence of polyelectrolytes and double hydrophilic block copolymers as crystal modifiers [1–7].
