Disclosed herein are a graphite crucible for electromagnetic induction- based silicon melting and an apparatus for silicon melting / refining using the same, which performs a melting operation by a combination of indirect melting and direct melting. The crucible is formed of a graphite material and includes a cylindrical body having an open upper part through which a silicon raw material is charged into the crucible, and an outer wall surrounded by an induction coil, wherein a plurality of slits are vertically formed through the outer wall and an inner wall of the crucible such that an electromagnetic force created by an electric current flowing in the induction coil acts toward an inner center of the crucible to prevent a silicon melt from contacting the inner wall of the crucible.

An upper surface layer 2 and a nonwoven fabric sound absorption layer 3 are integrally secured via an air permeable adhesive resin layer 4 formed by melting thermoplastic resin powder, and the air permeability of the thickness direction of the entire carpet 1 falls within the range of 1 to 50 cm3 / cm2·second. This effectively absorbs noise from the upper side entering via a roof, doors and windows as well as noise from the lower side. The carpet can be manufactured by scattering thermoplastic resin powder on an upper surface member, heating the thermoplastic resin powder into melted thermoplastic resin, placing a nonwoven fabric on the upper surface member via the melted thermoplastic resin, and pressing the nonwoven fabric and the upper surface member in a laminated state. It is preferable that powder of particle size of 90 to 10,000 μm is scattered in the amount of 5 to 500 g / m2.

The invention discloses a quaternary liquid metal heat interface material with dual melting points. The liquid metal heat interface materials adopt a three-layered foil-shaped structure, wherein the upper layer and the lower layer are made of 50% of indium, 18% of bismuth, 24% of tin and 8% of zinc by mole; the middle layer is made of 33% of indium, 26% of bismuth, 29% of tin and 12% of zinc by mole. A hole between a heating element and a radiator can be completely filled with the quaternary liquid metal heat interface material at a relatively low temperature after initial mounting, and then the quaternary liquid metal heat interface material is solidified due to diffusion. The quaternary liquid metal heat interface material is solid at normal working temperatures. When the temperature of an electronic device is raised to a design value, the quaternary liquid metal heat interface material can be melted twice to cool the electronic device sharply. Therefore, the quaternary liquid metal heat interface material has a wide application prospect.
