The crystallization process of iron-rich glass-ceramics prepared from the mixture of nickel slag (NS) and blast furnace slag (BFS) with a small amount of quartz sand was investigated. A modified melting method which was more energy-saving than the traditional methods was used to control the crystallization process. The results show that the iron-rich system has much lower melting temperature, glass transition temperature (T g ), and glass crystallization temperature (T c ), which can result in a further energy-saving process. The results also show that the system has a quick but controllable crystallization process with its peak crystallization temperature at 918°C. The crystallization of augite crystals begins from the edge of the sample and invades into the whole sample. The crystallization process can be completed in a few minutes. A distinct boundary between the crystallized part and the non-crystallized part exists during the process. In the non-crystallized part showing a black colour, some sphere-shaped augite crystals already exist in the glass matrix before samples are heated to T c . In the crystallized part showing a khaki colour, a compact structure is formed by augite crystals.

The effect of TiO2 and P2O5 on densification behavior and properties of Anortite-Diopside glass-ceramic substrates

In this work the synthesis of anorthite-diopside glass-ceramics (GCs) was carried out via sintering and crystallization of glass powder compacts in the temperature interval 800°C and 950°C. Glass powder compacts with mean particle size of 2 μm were prepared. The effects of adding TiO 2 and P 2 O 5 on the sintering behavior of glass powder compacts and on the properties of resultant glassceramics were studied. Mechanical, thermal, chemical and dielectric properties of sintered GCs were investigated with the aim to evaluate the potential of the GCs as substrate materials for microelectronics applications.

“…The glass transition temperature, T g , is constant for the three experiments and is equal to 335°C. The increase in the mean particle size from 6 μm (fine) to 167 μm (coarse) causes a shift of the crystallization peaks toward higher temperatures ranging from 420°C to 435°C, suggesting surface crystallization as the dominant mechanism in the investigated composition . The broadening of the crystallization peaks for the bulk as well as the study of Çelikbilek et al .…”

A Comprehensive Study of the Carbon Contamination in Tellurite Glasses and Glass‐Ceramics Sintered by Spark Plasma Sintering (SPS)

Highly transparent tellurite glasses and glass‐ceramics based on the 85TeO2–15WO3 composition (mol%) were produced by spark plasma sintering (SPS) from powders previously prepared by the conventional melt‐quenching technique and then grinded. We report a study based on the understanding of carbon contamination that is commonly observed by this nonconventional sintering technique and which constitutes a drawback for optical applications. First, the influence of the particle size of the initial amorphous powders as well as an additional pressureless sintering step prior to SPS experiments and the use of a physical carbon diffusion barrier have been investigated to reduce the carbon contamination in glass bulks. Second, once reducing the carbon contamination, glass‐ceramics were obtained by varying the SPS conditions. The noncentrosymmetric γ‐TeO2 phase crystallized within the bulk volume while maintaining good optical transparency and led to the generation of second harmonic. This approach paves the way to further applications in the domain of linear and nonlinear optics.
