A heating chamber (1) for a heating furnace is proposed, with which electrothermal vaporization of impurities from samples can be effected in order to be able to then analyze them spectrometrically. The heating chamber has a wall (3), a sample reception area (5), a nozzle area (7) and two electrical connection areas (9, 11). The heating chamber (1) is specially configured such that an electric current flows through the wall (3) in such a way that a heating capacity caused by it is higher in the nozzle area (7) than in the sample reception area (5). For example, the electrical connection areas (9, 11) may be arranged in a radial direction remoter from the longitudinal axis (8) than a part of the wall (3) surrounding the nozzle area (7), and the heating chamber (1) may be configured, for example by means of a locally constricted area (13), in such a way that the current between the two electrical connection areas (9, 11) is predominantly conducted radially inwards towards the part of the wall (3) surrounding the nozzle area (7). Advantageous heat distribution in the heating chamber (1) achievable thereby may have a positive effect on the analysis of sample impurities.

Disclosed is a sintering furnace comprising a furnace body and a lifting device, wherein the furnace body comprises a furnace chamber (10) and a furnace mouth (20), the furnace chamber (10) is connected with the furnace mouth (20), wherein the sintering furnace further comprises a sealing member (30) provided at the lifting device; when the sintering furnace is in a loading or unloading condition, the sealing member (30) blocks the furnace mouth (20). When the sintering furnace is in an unloading condition, the sealing member (30) can block the furnace mouth (20), the furnace chamber (10) does not contact with the outside directly, thus the temperature in the furnace chamber (10) will not drop sharply, and the service life of the sintering furnace will be increased.

A multi-chamber type heating unit to heat a blank includes: a lower housing unit; an intermediate housing unit installed in an upper portion of the lower housing unit; and an upper housing unit installed in an upper portion of the intermediate housing unit. A plurality of intermediate housings are stacked to form the intermediate housing unit, and a heating unit to heat a blank is installed in each of the intermediate housings. Moreover, the intermediate housings are formed in the shape in which upper and lower portions thereof are opened, and an opening is formed in the front for a door to be inserted thereinto, and door sealing units provided on the intermediate housing portion and provided to seal the door when the door is closed.

The present utility model relates to a graphite furnace locking device, comprising: a stationary part which is provided with a locking unit, a movable part which is arranged along a first direction facing the stationary part, the movable part being provided with a latch bolt unit; wherein, the movable part may move towards the stationary part along the first direction until the latch bolt unit and the locking unit are connected and then the locking device is in a locked state; the latch bolt unit provides a first elastic force for the movable part towards the direction of the stationary part; the locking unit is used to disconnect from the latch bolt unit, and then the locking device is in an unlocked state; the latch bolt unit provides a second elastic force for the movable part in a direction away from the stationary part, and the movable part can move away from the stationary part in the first direction under the action of the second elastic force to its initial position. For the locking device of the present utility model, when it is under an unlocked state, the movable part is automatically sprung away to prevent the operator from being injured by scalding.

The invention is a microwave gun and arc plasma torch furnace used to refine titanium, Ti, from titanium dioxide, TiO.sub.2, powder. The furnace includes high frequency microwave emitters that create a high temperature zone strongly vibrating the titanium dioxide powder, TiO.sub.2, and lengthening and weakening the valence bonds in the titanium dioxide powder, TiO.sub.2, titanium, Ti, and oxygen, O, atoms. The furnace also uses nitrogen arc plasma torch generators to generate a N.sup.+ plasma to completely disassociate the titanium, Ti, and oxygen, O, atoms into titanium ions, Ti.sup.+ and oxygen ions, O.sup., and permitting the formation of nitrogen dioxide, NO.sub.2, and melted titanium, Ti.
