The present invention includes a first injection tube for supplying a colloidal medium, a storage part connected to the first injection tube for receiving the colloidal medium through the first injection tube, a second injection tube connected to the storage part for supplying a colloid, a discharge tube connected to both the storage part and the second injection tube for discharging the colloidal medium coming from the storage part and the colloid coming from the second injection tube, and a free surface inversion part for inverting the free surface of the liquid in the second injection tube so as to mix the colloidal medium and the colloid in the discharge tube.

Apparatus for producing a composite material

Disclosed is an aluminum alloy for die casting which comprises 1.0 weight % to 2.0 weight % of magnesium (Mg), 0.5 weight % to 1.6 weight % of iron (Fe), and 0.5 weight % to 0.9 weight % of silicon (Si), with the remainder being aluminum (Al) and inevitable impurities.

Disclosed are a method and an apparatus for fabricating solar-grade high purity polycrystalline silicon compacts. Silicon compacts are fabricating by loading polycrystalline silicon powders into a mold without addition of binders in a vacuum atmosphere, and pressurizing and heating the polycrystalline silicon powders. Heating method includes a high-frequency induction heating type, an Ohmic heating type, and a high current supply type.

Disclosed is an electromagnetic continuous casting apparatus for a material having a low electric conductivity. The casting apparatus includes a crucible having a vertical axis. The crucible comprises an upper hot crucible and a lower cold crucible. The crucible is surrounded with an induction coil. The hot crucible is formed of a non-metallic material having a high electric conductivity and is not water-cooled. The cold crucible has a cooling structure and is formed of a metallic material having a high thermal conductivity and a high electric conductivity.
