In 1968, Stöber et al. [55] developed a process capable of forming controlled silica particles (500 nm-2 μm) using tetraethoxysilane (TEOS) as silica precursor, water, ethanol and ammonia. The process was carried out at room temperature and higher pH (~ 10). The silica particles had a narrow size distribution and could be controlled by ...

A float line is almost like a river of glass that exits the furnace before its cooling process. It makes its way to nearly 300 meters, after which it is cut into large sheets; these sheets typically measure 3.21x2.25 meters. Hence a float line is capable of continuously producing glass round-the-clock.
Several factors determine the optimal Flo-Gard silica for a given anti-caking/free-flow application. These include powder flow behavior, the mechanisms through which powder flow behavior can be improved, and customer-specific product and process details and conditions. Generally, powder flow behavior is determined by:
Heavy mineral sands are the source of various commodities such as white titanium dioxide pigment and titanium metal. The three case studies in this paper show the value of X-ray diffraction (XRD) and statistical methods such as data clustering for process optimization and quality control during heavy mineral processing. The potential of XRD …

Float glass is a type of sheet glass, made by a process invented in the 1950s by Sir Alastair Pilkington. It is created by floating molten glass on a bed of molten metal, usually tin, which is then cooled and formed into a sheet. This process gives the glass its smooth, even surface, and also eliminates the need for grinding or polishing on one ...
Partitioning and transmutation of minor actinides (MA: Np, Am, Cm) in spent nuclear fuel is essential strategy for reduction in volume and radio toxicity of nuclear wastes [].Japan Atomic Energy Agency has been proposing NEXT process (Fig. 1 []) for reprocessing of spent fast reactor fuels.In this process, Np can be recovered with U and …

Floating is possible because the density of a typical soda-lime-silica glass (~2.3 g/cm 3) is much less than that of tin (~6.5 g/cm 3) at the process temperature. After cooling and annealing, glass sheets with uniform thicknesses in the ~1–25 mm range and flat surfaces are produced. The float glass process is used to produce virtually all ...
