electric melting process of silica and glass, in order to obtain fused masses, of textile fibres and insulating, and furnace for implementing the method.
Optical losses in silica glass fibers remain a challenge in their applications. The main contributor to optical attenuation is Rayleigh scattering. This re... M Ono - 《Journal of Lightwave Technology》 被引量: 0发表: 2021年 MELTING METHOD DURING FLOATING-ZONE GROWTH OF SILICON in the form of...
Decreasing temperature and loss of dissolved water lead to polymerization of silica tetrahedra (SiO4) in the melt that are the building blocks of common volcanic minerals like quartz (SiO2), plagioclase feldspars (Ca/Na–Al silicates), alkali feldspars (Na–K–Al silicate), olivine (Mg/Fe ...
Quartz-deficient aluminous rocks can either be derived from low-silica, initially clay-rich, protoliths or generated at high-T to UHT conditions through the production and loss of melt formed through dehydration-melting reactions involving biotite. The minimum temperatures and P-T domains of quartz...
The dependence of silica sand composition on its granularity is discussed through analysis of its grain distribu tion and the effect of granularity or composition onmeltis al so pointed out . 通过对硅砂颗粒度的分析,介绍了硅砂成份与颗粒度的关系,说明了硅砂对熔化的影响。

The typical way of constructing fixed-point cells is very well described in the literature. The crucible is loaded with shot, or any other shape of pure metal, inside an argon-filled glove box. Then, the crucible is carefully slid into a fused-silica tube that is closed at the top with...
This study investigates the use of Diode Area Melting (DAM) to process 316L stainless steel (SS316L), an alternative to Laser Powder Bed Fusion (LPBF), uti
Final polishing was performed using an alumina suspension for porosity analysis and subsequently with a 0.04 μm colloidal silica suspension for electron backscatter diffraction (EBSD) measurements. For the porosity measurements, the samples were polished such that only the pores present could be ...
This process requires the production, segregation and migration of silica-rich (felsic) melts from deeper source rocks to shallower sinks where they erupt or, more commonly, crystallise as granite sensu lato. Evidence of partial melting and drainage of melt from crustal rocks is Funding T.E.J ...
