“…Lima et al 57 produced glass‐ceramics from FSG basalt by the sinter‐crystallization process and Klein et al 58 by the bulk crystallization process. Both TTs promoted the formation of crystals in the form of submicrometric spheroid crystals, and the presence of dendritic structures, such as those obtained in this work, for the same rock, was not observed, corroborating the fact that dendritic structures arise with the particular TT applied in the petrurgic method.…”

Basalt glasses may form glass‐ceramic materials upon a thermal treatment (TT) if the Fe2O3/FeO ratio is greater than 0.5. In this work, a Serra Geral Formation basalt was used to produce different glass‐ceramic materials by changing its chemical composition, removing Fe2O3 via magnetic separation and adding 20 wt% Fe2O3. Glass‐ceramics were prepared by melting at 1500°C, followed by a crystallization plateau at 950°C. This petrurgic TT yields dendritic structures upon surface crystallization. With the increase of the iron content, crystallization was more pronounced, as observed in thermal analysis results and optical/scanning electron microscopy. The microstructure analysis shows that these glass‐ceramics exhibit at least two different types of crystallization. On the surface, the predominant crystallization was dendritic, while in bulk, crystallization occurred in the form of randomly distributed submicrometric spheroid crystals.

Glass-ceramics were fine-grained polycrystalline materials produced by controlled crystallization in the glass phase to have outstanding characteristics. The establishment of basalt from Sukadana -Lampung Province into glass-ceramic begins with the process of reduced size and milled under 200 mesh using an ASTM sieve. The initiated glass-ceramics formation was created by melting the basalt powder at a temperature of 1,250 o C for 2hrs to obtain the glass phase. Glass parent crystallization begins with the stage of nucleation growth. The nucleation process occurs at a temperature 600 o C for 1hr. The crystallization temperature at variations of 850, 950, or 1,050 o C for 3 and 8hrs. The mechanical hardness test result was 637.28 HV1N of the sample with 1,050 o C heating for 3hrs. The highest hardness value is at 837.33 HV1N for a sample of 1,050 o C heating for 8hrs. The hardness value was decreased at samples for 3hrs heating, while it increased for 8hrs of a heating process. All of the heating treatments formed olivine and Anorthite phase but a pyroxene phase was initiated from 950 o C heating process for 3hrs. The use of glass ceramic as an engineering material and biomaterials are promising. It is necessary to continue the development studies on the production process of local basalt resources.

“…Moreover, basalts can be used as raw materials for obtaining iron-rich glass and glass-ceramic materials V. Pavkov et al / Processing and Application of Ceramics 16 [2] (2022) 143-152 [19][20][21][22][23][24] due to their chemical composition since these volcanic rocks are mainly composed of silica, alumina, iron oxide, calcium oxide and magnesia with lower content of potassium, titania, manganese and phosphorus oxide [14]. Classification of basalt rocks is conducted according to the SiO 2 content present in their composition and thus basalts can be classified as alkaline (up to 42% SiO 2 ), mildly acidic (43-46% SiO 2 ) and acidic (over 46% SiO 2 ) [25].…”

In the present study, andesite basalt originated from the deposit site ?Donje Jarinje?, Serbia, was examined as a potential raw material for high-density ceramics production. The production of high-density ceramics included dry milling, homogenization, cold isostatic pressing and sintering in the air. To determine the optimal processing parameters the sintering was conducted at 1040, 1050, 1060, 1070 and 1080?C, and afterwards the sintering duration was varied from 30 to 240min at the optimal sintering temperature of 1060?C. Characterization of the starting and sintered materials included the estimation of particle size distribution, density, hardness and fracture toughness complemented with X-ray diffraction, optical light microscopy, scanning electron microscopy and energy dispersive spectroscopy analysis. Phase transformations did not occur during processing in the investigated temperature range from 1040 to 1080?C. The obtained research results showed that 99.5% of relative density and the highest hardness and fracture toughness values of 6.7GPa and 2.2MPa?m1/2, respectively, were achieved for the andesite basalt sintered at 1060?C for 60min in the air. The results of the present study confirmed that the sintered andesite basalt can be used as a high-density ceramic material for various industrial applications.
