“…For example, the presence of clino-and orthopyroxenes in metamorphosed mafic rocks defines the granulite facies [5][6][7] , they are common components in a wide variety of igneous rocks 8 , and pigeonites were found to be important components of lunar samples 9 . Pyroxene compositions have also been used for the fabrication of glass-ceramics [10][11][12][13] , and phosphors 14 . The pyroxene structure is more polymerized than that of the olivines, as it is a single-chain silicate with two octahedral sites located between the chains.…”

Olivine is a relatively common family of silicate minerals in many terrestrial and extraterrestrial environments, and is also useful as a refractory ceramic. A capability to synthesize fine particles of olivine will enable additional studies on surface reactivity under geologically relevant conditions. This paper presents a method for the synthesis of nanocrystalline samples of the magnesium end-member, forsterite (MgSiO) in relatively large batches (15-20g) using a sol-gel/surfactant approach. Magnesium methoxide and tetraethylorthosilicate (TEOS) are refluxed in a toluene/methanol mixture using dodecylamine as a surfactant and tert-butyl amine and water as hydrolysis agents. This material is then cleaned and dried, and fired at 800°C. Post-firing reaction in hydrogen peroxide was used to remove residual organic surfactant. X-ray diffraction showed that a pure material resulted, with a BET surface area of up to 76.6m/g. The results of a preliminary attempt to use this approach to synthesize nano-scale orthopyroxene (MgSiO) are also reported.

“…Despite these disadvantages of CSP technologies, due to the possibility of this technology to achieve high temperatures, up to 3000 degrees, CSP technologies have found wide applications in the world. For example, as noted in [11], CSP is a highly competitive technology for generating electricity, research in the field of solar materials science is known and relevant, in particular the successes of scientists from France and Uzbekistan [12][13][14][15][16][17][18][19][20]. The paper [20] provides a brief overview of the dynamics of the development of solar energy concentration technologies in the world in the period from 2010 to 2021 and assesses the possibility of using these technologies in Uzbekistan.…”

The paper examines the state and prospects for the development of renewable energy use in Uzbekistan, presents the specific features and conditions of concentrated solar power (CSP) technology, analyzes the technological capabilities of high-temperature solar furnaces as one of the promising areas of CSP technology, and notes specific scientific directions in this area. A comparative analysis of the technical and optical-energy characteristics of high-temperature solar furnaces of well-known research centers and their application in solving of actual scientific and technical problems is carried out. The main parameters and energy characteristics of the Uzbek 1000 kWt solar furnace in Parkent (BSF) in comparison with the similar French (Odeillo) furnace are given. Special equipment and stands installed in the focal zone of the furnace for melting, synthesis, heat treatment and complex testing of various technical products in high-temperature conditions are presented. By the example of the analysis of the process of quenching high-temperature materials, some features of high-temperature processes are shown.
