“…If the n value is close to 3, that denotes the bulk crystalline mechanism and two-dimensional growth. If the n value is close to 4, that denotes the bulk crystalline mechanism and three-dimensional growth [26,27]. The Avrami parameters (n) for the crystal growth of the GC0-GC9 samples under various heating rates are shown in Table 9, respectively.…”

In the paper, glass ceramics used as architectural materials were prepared based on lead fuming furnace-slag (LFFS) by a synergistic sinter-crystallization method. The effects of Al2O3 addition on the crystallization phase, crystallization kinetics, and mechanical performance of glass ceramics were investigated. The results showed that the phases of the glass ceramics prepared were composed of gehlenite and wollastonite, and crystallization kinetics analysis showed that bulk crystallization dominated the overall crystallization process in the Al2O3 content range from 2% to 8%. The glass transition temperature and the crystallization peak temperature of the glass ceramics generally increased with the increase in the Al2O3 content. Additionally, the crystalline morphology gradually developed from sheet-like to spherical, while the number of pores increased and the bulk density gradually decreased. When the Al2O3 content was 2%, the bending strength of glass ceramics reached its maximum, 75.1 MPa, corresponding to a bulk density of 2.24 g·cm−3. Owing to the high strength and relatively low bulk density, the sintered glass ceramics appear promising for potential applications in lightweight construction tiles.

“…In general, the investigation of isothermal growth behaviors can be realized by Johnson−Mehl−Avrami−Kolmogorov (JMAK) model [11][12][13][14][15] or Kissinger method [16] based on the differential scanning calorimetry (DSC) data and scanning electron microscope (SEM). The analysis and research of growth behaviors through the JMAK model are carried out from the theoretical level.…”

Calcium pyroniobate (Ca2Nb2O7) as a kind of lead‐free piezoelectric material has been applied for different fields, but the study of isothermal and non‐isothermal growth behaviors of Ca2Nb2O7 in the molten slag is infrequent. In this paper, the in situ thermal analyzer with a single hot thermocouple technique (SHTT) is used to study the growth behaviors of Ca2Nb2O7 in molten slag. In the isothermal temperatures, the Ca2Nb2O7 presents two kinds of growth morphology, including three dimensional (3D) rhombus growth and fibrous one dimensional (1D) growth. The 3D rhombus is grown under the range of 1608 to 1628 K. When the temperature further decreases to 1593 K, the growth behavior of Ca2Nb2O7 becomes fibrous in 1D. Growth velocity affected by the degree of supercooling may account for the phenomenon of two kinds of growth behaviors in different temperatures. In the non‐isothermal growth process, the cooling rate over 10 K min−1 contributes to multiple crystal nucleuses growth of Ca2Nb2O7. The cooling rate below 5 K min−1 leads to single nuclear growth. This paper provides a control guideline for Ca2Nb2O7 growth.
