Described herein is a crucible with a rod fused thereon to optimize pouring of molten material, and method of using the same. The crucible has a body configured for receipt of an amorphous alloy material in a vertical direction, and the rod extends in a horizontal direction from the body. The body of the crucible and the rod are formed from silica or quartz. The rod may be fused to the body of the crucible and provided off a center axis so that pouring molten material is improved when the crucible is rotated.

A pot furnace for calcining petroleum coke at low temperature may include a pot, and a cooling water jacket and a flame path below the pot. The flame path may include eight layers. An inlet of a first flame path layer may be in communication with a volatile channel in the front wall, and is provided with a first flame path layer flashboard. An eighth flame path layer may be in communication with a communication flue. Flue gas may be discharged out of the furnace body through a main flue. A furnace bottom cooling channel may be provided below the eighth flame path layer.

An ion implanter includes a crucible provided inside a vacuum chamber, and including an internal space configured to accommodate a solid sample which is a raw material of a source gas, a laser source provided outside the vacuum chamber, and irradiating the crucible with a laser beam, an arc chamber including an internal space for converting the source gas into plasma to generate ions, and in which an ion beam is extracted from the internal space, and a nozzle connecting the internal space of the crucible and the internal space of the arc chamber, and introducing the source gas vaporized in the internal space of the crucible into the internal space of the arc chamber.

The application basically comprises supplying a high-temperature ultra-high vacuum furnace, the sole chamber of which is metal, in which an electrically conductive crucible, preferably made of tantalum, is placed onto an insulating support, preferably a ceramic, and is induction heated by a winding wound around the crucible. The insulating tube, preferably made of quartz, that is arranged between the induction winding and the crucible, advantageously acts as a surface on which the condensable species can condense. The quartz insulating tube especially allows the induction winding to be protected.

A device for producing purified, especially high-purity, magnesium includes a reactor for vacuum distillation that is extended along a longitudinal axis (L). The reactor defines a reactor inner chamber having a heating region for heating magnesium. A crucible forms a crucible inner chamber for receiving purified magnesium vaporized and condensed by the device. A radial projection in the heating region defines a contact surface that extends essentially transverse to the longitudinal axis (L) and forms an essentially sealed connection with an edge of the crucible adjacent to the crucible inner chamber.

A system for treatment of a first material with at least one hazardous material, the system comprising a manufacturing room configured according to safety standards to hold at least one hazardous material. The manufacturing room is configured for the treatment of the first material using the at least one hazardous material as a solvent. A holding room is not configured according to the safety standards and is separated from the manufacturing room by a wall common to the manufacturing room and the holding room. A vacuum oven is embedded in the wall, and has a rear portion in the manufacturing room and a front portion in the holding room. The front door of the oven is configured to be opened from the holding room for removing the first material from the inner cavity following removal of the at least one hazardous material from the first material and from the inner cavity and no electrical components of the vacuum oven extend into the manufacturing room.

A metal forming apparatus includes a smelting device, a molding device, an injection device and a vacuumizing device. The smelting device defines a smelting chamber, and includes a rotatable crucible and a heating unit both disposed within the smelting chamber. The molding device defines a molding chamber sealedly communicated with the smelting chamber. The injection device includes a charging barrel assembly sealedly disposed at a joint between the molding device and the smelting device and an injection unit sealedly connected with the smelting device. The vacuumizing device is sealedly connected with the smelting device and the molding device respectively so as to vacuumize the smelting chamber and the molding chamber.
