The monolithic lining solution for ferroalloys furnaces has developed from the use of hot ramming pastes with coal tar pitch binder, to cold ramming pastes with less harmful components, or non-harmful components. New materials demand improved install

Multicrystalline silicon displays a considerable smaller average grain size and reduced dislocation generation when being seeded by polycrystalline silicon chips or fluidized bed reactor silicon granules. A simple texture analysis shows how the initi

Bi-crystal silicon ingots with coincident site lattice (CSL) grain boundaries (GB), namely Σ3, Σ9, Σ27a, have been grown in a small scale Bridgman type furnace at 3 µm/s. Melts have been intentionally polluted with 25 ppma of copper and indium. S

Small-scale solidification simulations were carried out in order to study the effect of the grain orientation and cooling rate on the stresses in mono- and bi-crystals. First, a 2D-axisymetric heat-transfer model of the global furnace is established

Small angle grain boundaries have been grown in a small Bridgman furnace, using seeded growth method, at three different pulling rates i.e. 3 μm/s, 13 μm/s and 40 μm/s. In order to assess segregation mechanisms of impurities towards the central gr

In this study, the influence of pulling rate on lifetime and impurity distribution in multicrystalline silicon has been investigated. Ingots have been pulled at different rates in a small scale Bridgman type furnace and were intentionally polluted wi
