Synthesis of Perovskite by Solid-Phase Method with Metatitanic Acid and Calcium Carbonate and Its Pigment Properties Investigation
Synthetic perovskite powder (SPP) was synthesized by the solid-phase method using metatitanic acid (TiO(2)·nH(2)O) and calcium carbonate (CaCO(3)) as raw materials, and its structure, morphology, pigment properties and application in architectural coatings were studied. When TiO(2)·nH(2)O and CaCO(3...

description | Synthetic perovskite powder (SPP) was synthesized by the solid-phase method using metatitanic acid (TiO(2)·nH(2)O) and calcium carbonate (CaCO(3)) as raw materials, and its structure, morphology, pigment properties and application in architectural coatings were studied. When TiO(2)·nH(2)O and CaCO(3) were mixed and ground at a molar ratio of TiO(2):CaO = 1:1, and then calcined at 900–1100 °C, SPP with a single perovskite phase was obtained. The characterization results displayed that the unit particle size of SPP was 50–150 nm, the aggregate size was 1–2 μm, and its particles were well dispersed. The SPP also had a whiteness of 90.5%, and an oil absorption of 35.03 g/100 g. The hiding power of SPP was 24.02 g/m(2), which was 81.6% of pure TiO(2) hiding power (19.60 g/m(2)). When adding SPP to prepare a building exterior wall coating, the contrast ratio of the coating film was 0.92, which met the requirements of the Chinese national standard GB/T 9755-2014 and was equivalent to adding rutile titanium dioxide. Thus, perovskite synthesized from TiO(2)·nH(2)O and CaCO(3) by the solid-phase method significantly improved the pigment properties of TiO(2) in the same proportion. |
