Sonochemical Synthesis of Vaterite-Type Calcium Carbonate Using Steamed Ammonia Liquid Waste without Additives

Abstract

Herein, metastable spheroidal vaterite calcium carbonate (CaCO3) was prepared using a simple ultrasound technique. The fabricated material comprises an irregular nanoparticle aggregate when steamed ammonia liquid waste, that is, (CaCl2) and (NH4)2CO3, is used as the raw material at atmospheric temperature, without any surfactants. The effects of ultrasound amplitude, probe immersion depth, and solution volume on particle properties were investigated. The obtained samples were identified and characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and the Brunauer–Emmett–Teller technique. Our experiments show that the probe immersion depth and the reaction volume are the key parameters that impact the diameter size and size distribution of the fabricated spheroidal vaterite CaCO3 particles. The ultrasound amplitude considerably affected the particle size and the specific surface area. A possible formation mechanism for pure vaterite is proposed herein, which suggests that simple vaterite CaCO3 is formed owing to the special properties of steamed ammonia liquid waste and the synergistic effects of the ultrasonic system. This study may provide a new method for vaterite CaCO3 synthesis.

Size Control of Biomimetic Curved-Edge Vaterite with Chiral Toroid Morphology via Sonochemical Synthesis

“…Amino acids promoted the formation of curved-edge vaterite with chiral torotid morphology (chiral-curved vaterite), while US irradiation led to the formation of smaller chiral-curved vaterite. US irradiation mediated the formation of the vaterite phase, surpassing the formation of both the calcite and aragonite forms [ 49 ]. The addition of acidic amino acids resulted in the formation of chiral-curved vaterite.…”

Feasible calcium carbonate polymorphs synthesis from natural corallines and their potential gelling role in hydraulic fracturing application

“…(i.e., aragonite, calcite, and vaterite) [3,4] The thermodynamics viewpoint reveals the highest stability of the rhombohedral calcite phase and the reduced stability of the hexagonal vaterite phase [5]. The calcium carbonates might be presented to production using numerous methods and chemical precursors such as the sonochemical approach [6], co-precipitation [7], and microwave-aided procedure [8]. Calcium carbonates deliver numerous potential applications in fillers, paints, plastics, cosmetics, water treatment, drug delivery systems, the food industry, and so on [9][10][11][12][13][14] These potential applications are promoted by the fact of the enriched and elevated surface area, dispersion, biocompatibility, biodegradability, and porosity.…”

Biogenic calcium carbonate derived from waste shells for advanced material applications: A review

“…It is interesting to note that all of those structures naturally exist. They can also be synthesized or precipitated with different morphologies or sizes and convert to other polymorphs structures by several techniques such as microwave-assisted (Qi and Zhu, 2006;Qi et al, 2014;Skubiszewska-Zięba et al, 2017), carbonation (Hou and Feng, 2005;Beuvier et al, 2011;Udrea et al, 2012;Lai et al, 2015;Yuan et al, 2015), sonochemical (Zhou et al, 2004;He et al, 2005;Luo et al, 2021), hydrothermal (Zhao et al, 2011;Sulimai et al, 2017) and wet precipitation technique (Brečević et al, 1996). The neat calcium carbonate from eggshells exists in the calcite structure.…”
