.... At this point, the initial charge volume is reduced to that of the molten metal, and the furnace may be opened and the remaining portions of the charge added (the recharge). This additional charge is melted by the arcs until the entire bath is molten. Further heating of the melt may now be done by blowing...

... ]. Beryllium differs from most metals in that it has a relatively high melting point (1287 °C), a high latent heat of fusion (7.895 kJ/mol), and a low thermal conductivity (200 W/m · K). Because of the combined effects of these properties, heat removal during solidification becomes difficult. This difficulty...
