“…In nature, carbonates are found in many minerals and play a crucial role in the carbon exchange of our planet [ 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. Carbonate compounds are widely used in the construction industry, optics, and nanotechnology [ 9 , 10 , 11 , 12 , 13 , 14 , 15 ]. Appearance of the carbonate species due to chemical interaction with the atmosphere agents was detected at the surface of many oxide materials widely used in optical and electronic technologies [ 16 , 17 , 18 , 19 , 20 ].…”

Within the framework of the density functional theory (DFT) and the hybrid functional B3LYP by means of the CRYSTAL17 program code, the wavenumbers and intensities of normal oscillations of MgCO3, CaCO3, ZnCO3, CdCO3 in the structure of calcite; CaMg(CO3)2, CdMg(CO3)2, CaMn(CO3)2, CaZn(CO3)2 in the structure of dolomite; BaMg(CO3)2 in the structure of the norsethite type; and CaCO3, SrCO3, BaCO3, and PbCO3 in the structure of aragonite were calculated. Infrared absorption and Raman spectra were compared with the known experimental data of synthetic and natural crystals. For lattice and intramolecular modes, linear dependences on the radius and mass of the metal cation are established. The obtained dependences have predictive power and can be used to study solid carbonate solutions. For trigonal and orthorhombic carbonates, the linear dependence of wavenumbers on the cation radius RM (or M–O distance) is established for the infrared in-plane bending mode: 786.2–65.88·RM and Raman in-plane stretching mode: 768.5–53.24·RM, with a correlation coefficient of 0.87.

“…Bone, meal and feather fillers can be produced for 4.4, 4.3 and 3.2 p/kg respectively. This is notably lower than for common polymer fillers such as calcium carbonate (purchase price of between 31 -39 p/kg (Lee et al, 2020)), talc (12 -51 p/kg (Gonzalez De Gortari et al, 2020)) or kaolin (13 p/kg (Jafari et al, 2020)). The final cost of poultry waste polymers is also lower than for oil-derived polymers, i.e.…”

“…[20][21][22] Nowadays, researches on improving the TSR of castables are mostly concentrated on adding micro powders to the matrix. [13][14][15][16][17][18] However, in-situ formed CA 6 particles in these researches were randomly distributed in the matrix and the matrix-aggregates interface is neglected. Meanwhile, it is found that the addition of water-soluble calcium chloride can also improve the TSR of castables, but the value of CCS and cold modulus of rupture (CMOR) of castables are reduced due to the formation of more pores, 23 In addition, substituting the plate-shaped corundum aggregates (3-1 mm) with CA 6 particles in same size can improve the fatigue resistance of castables, but the fatigue resistance of castables containing 5-3 mm CA 6 particles is poor.…”

“…Ref. 16–18 introduced nano‐CaCO 3 powders into the castables. The nano CaO produced by the decomposition of nano CaCO 3 powders has larger specific surface area, higher reaction activity and more lattice defects resulting a more complete in‐situ formation of CA 6 , therefore the castables containing CaCO 3 nano powders exhibit higher flexural strength.…”

Al 2 O 3 @CaCO 3 aggregates were prepared by impregnating corundum aggregates (particle sizes with 3-1 and 5-3 mm) in precursor solutions (Calcium hydrogen citrate, CaHC 6 H 5 O 7 ) followed by heat treatment at 430°C. The phase composition and microstructure of the coatings were characterized via X-ray diffraction and scanning electron microscope, respectively. The novel aggregates were used in Al 2 O 3 -MgO castables. The effects of the Al 2 O 3 @CaCO 3 aggregates on the physical properties and thermal shock resistance (TSR) of castables were investigated. The results show that uniform CaCO 3 coating of aggregates (C15) with thickness about 10 µm can be attained when the concentration of Ca 2+ in solution was 0.15 mol L −1 . There was a strong bonding between the aggregates and coating that was constituted by particles with size about 0.2 µm. Both improving physical and TSR properties of the castables are related with the unique layer structure, calcium hexaluminate (CA 6 ) layer in-situ formed at the aggregate-matrix interface, of added Al 2 O 3 @CaCO 3 aggregates. There is a mass of multi-deflection of cracks along with the CA 6 layer which consumes more fracture surface energy. The castables with C15 exhibit optimal TSR and the residual strength ratio after the thermal shock test is 29.5%, which is 12.8% higher than the castables with corundum aggregates.
