— The processes of melting of different types of igneous rock constituting gabbro-basalt raw material are examined. The role of the main rock-forming elements in the formation of these melts for the production of mineral fibers and stone-cast articles is shown. Special attention is devoted to their influence on the viscosity and crystallizability …
Melt cast basalt is a useful material for floor tiles and similar abrasion-resistant products obtained by melting natural basalt rock and casting into molds. It is a possible candidate …
— Here we report density functional theory-based simulations of model basalt, hydrous model basalt and near-MORB to assess the …
— Close to it is the cast basalt production of the company EUTIT s. r. o. (Stará Voda, Cheb, Czech Republic). The manufacturing starts with melting the rock at 1280 °C [3]. It is then cast into moulds and cylinders, which will then be put into kilns at 850 °C for thermal treatment, forcing the basalt to recrystallize and change its properties.
— Basalt is a unique material because it can be both sculpted and cast in molds and processed to obtain discontinuous or continuous fibers. These are analyzed in a peculiar way, reporting expert studies and analyses with the aim of defining its properties (morphology, mechanical properties, thermal properties, corrosion resistance, and …
— Basalt, a fine grained igneous rock, would be fine. It would still need quite a long cool down time. ... $begingroup$ Thanks for the correction. cast iron does have a lower melting point than pure iron. 13th century for a blast furnace is late medieval to early renaissance technology, so it still doesn't qualify as advanced technology. $endgroup$
— Semantic Scholar extracted view of "Phase distribution of uranium in matrices obtained by co-melting basalt and uranium-containing aluminum oxide" by K. Martynov et al. ... The distribution of uranium between different phases of cast stone matrices fabricated by fusion of basalt and uranium-bearing SiO2-based collectors was investigated. It was ...
— The product was basalt cast with the following dominant composition is MgO 5.244%, Al 2 O 3 21.295%, SiO 2 48.750, CaO 10.138%, Fe 2 O 3 11.019%, TiO 2 1.361% and Na 2 O 2.132%. ... The process of ...

— These phenocrysts usually are of olivine or a calcium-rich plagioclase, which have the highest melting temperatures of the typical minerals that can crystallize from the melt. Basalt with a vesicular …
— This paper describes the melting relations of three basalts, a Picture Gorge tholeiite, the 1921 Kilauea olivine tholeiite, and the 1801 Hualalai alkali basalt, at 5 kb …
The heat capacities of the liquid, glassy and crystalline phases of an alkali basalt have been deter-mined from relative enthalpies measured between 400 and 1,800 K. Values given …
— The units welded for this study as an analogue for cast mare regolith were 20 × 35 × 40 mm blocks cut from cast basalt tiles ( Fig. 3 ). This allowed large numbers of blocks to be produced ...
— Abstract The distribution of uranium between different phases of cast stone matrices fabricated by fusion of basalt and uranium-bearing SiO2-based collectors was investigated. It was found that matrices created by fusion of basalt with SiO2 consist of glass, quartz, and spinel as the main phases. A study of the physicochemical properties …
— Sample return missions have provided the basis for understanding the thermochemical evolution of the Moon. Mare basalt sources are likely to have originated from partial melting of lunar magma ...
