“…78-0209) [1]. It is widely utilized in ceramic industry colorants [2], organic industrial catalysts [3], lithium ion battery cathode materials [4,5,6,7,8], and precursors [9,10,11,12], including those precursors for the cemented carbides industry [13,14,15]. The synthesis method of cobalt carbonate include the hydrothermal process [13], solvothermal process [16], as well as batch or continuous methods of the carbonate or bicarbonate precipitation process [17,18,19].…”

Spherical CoCO3 powder with a small particle size and high density was successfully prepared using a continuous carbonate liquid precipitation method with a raw material of cobalt chloride solution, a precipitant of NH4HCO3, and without a template. The effects of the concentration of ammonium carbonate, process pH, and feeding rate on the tap density and apparent density of cobalt carbonate were investigated. It was found that the apparent and tap density values of 4.4 µm of cobalt carbonate were 1.27 g/cm3 and 1.86 g/cm3, respectively, when the initial concentration of NH4HCO3 solution was 60 g/L, the pH was 7.15–7.20, and the feeding rate of cobalt chloride was 2 L/h. The anisotropic growth process of the crystal lattice plane of CoCO3 under the aforementioned optimal conditions were studied. The results demonstrated that the crystal grew fastest along the (110) facet orientation, which was the dominant growth surface, determining the final morphology of the primary particles. The scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (HR-TEM) results demonstrated that the primary particle morphology of the cobalt carbonate was a nanosheet. The unit cell of cobalt carbonate, of a hexagonal structure in the horizontal direction, grew horizontally along the (110) facet orientation, while 20–35 unit cells of the carbon carbonate were stacked along the c-axis in the thickness direction. Finally, the sheet-shaped particles were agglomerated into dense spherical secondary particles, as presented through the crystal re-crystallization model.

“…In this respect, it is important to monitor the crystal growth kinetics. HT XRD, DSC and DTA methods are well known and very often used for glass crystallization study [17][18][19][20][21][22][23][24][25] and for study of thermal behavior of many kinds of materials. HT XRD analysis was successfully used for study of phase development in many systems [5,22,23,[26][27][28][29][30] and for determination of conversion rate dependence on temperature in yttrium-aluminate glasses and lanthanum-aluminate glasses [5,10,28,29].…”

“…At the same time, it also can be used as infrared radiation base materials, served in the environment of high temperature, but the YAG has a poor radiation performance at near infrared waveband. 14) However, we can improve its infrared emission property by means of ions doping. Han Zhao 10) et al Research showed that when the Ca 2+ ions substituted La 3+ ions in LaCrO 3 perovskite structure, for maintaining the charge conservation, a small amount of Cr 3+ ions would be transformed into Cr 4+ ions and Generated the impurity level which would effectively reduce the width of the forbidden band and strengthen the infrared absorption and radiation of materials.…”
