Glass and bioglass nanopowders by flame synthesis.
The preparation of amorphous nanopowders by flame synthesis opens access to common soda-lime, metal-doped glasses or bioglasses in the range of 20-80 nm and offers an alternative to conventional wet-phase preparation, solid state reactions or melting.
متن کاملThe industrial glass melting process
The glass melting process starts from a granular mixture of natural and synthetic raw materials (the so-called batch) and yields a thermally and chemically homogeneous melt made available at a well defined temperature level. The consecutive steps of glass fabrication (forming, annealing, etc.) are not within the scope of interest of this paper. Figure 1 illustrates how a continuously working gl...
متن کاملModelling of glass melting industrial process
The present paper emphasizes the potentialities of the industrial use of three-dimensional mathematical modelling of glass melting tanks for optimization of working conditions, design and control of indusaial furnaces. A short review of related recent relevant works is presented and industrial needs and requirements in modelling are discussed. A modelling procedure to solve the heat and mass tr...
متن کاملShear melting of a colloidal glass.
We use confocal microscopy to explore shear melting of colloidal glasses, which occurs at strains of approximately 0.08, coinciding with a strongly non-Gaussian step size distribution. For larger strains, the particle mean square displacement increases linearly with strain and the step size distribution becomes Gaussian. The effective diffusion coefficient varies approximately linearly with she...
متن کاملThree-Dimensional Flow and Thermal Structures in Glass Melting
This paper presents a study of the flow and thermal structures in the molten glass bath of a typical glass melting furnace with a throat but without air bubblers or electric boosting. Different separate effects on the flow structure of the glass melt are simulated, but only the glass melt is considered. The net heat flux distribution is imposed at the combustion space/glass melt interface, and ...
