Abstract
The utility model provides a high-temp. Ceramic crucible which relates to an experimental ceramic crucible which is used for high-sintering, high-temperature chemistry synthesizing, etc. The utility model is characterized in that: the crucible respectively comprises a crucible top cover, a crucible bottom and a crucible wall. Wherein, a dummy club is arranged on the underside of the crucible top cover. Another dummy club is arranged on the upper end face of the crucible bottom. The upper and the lower ends of the inner wall of the crucible wall are respectively provided with ledge structures which are clearance inserted and fitted. The height of the ledge structures is the same as the outer diameter of the crucible top cover and the height of the crucible bottom. The utility model adopts the structures of false bottom and detachable cover so that each part of the crucible is able to freely expand and shrink when the temperature of the crucible lifts and drops. The crucible breakage caused by stress concentration can be avoided. The heat-proof quality of the crucible can be improves and service life is prolonged.
Description
Technical field
A kind of high-temperature ceramic copple relates to a kind of ceramic crucible that is used for test production processes such as high temperature sintering, high temeperature chemistry be synthetic.
Background technology
The high temperature sintering of many materials, the chemical reaction under the high temperature need be contained in the interior high temperature furnace of resistant to elevated temperatures crucible and carry out.This class ceramic crucible has corundum, spinel, mullite, green stone matter, clay matter etc.Ceramic crucible has advantages such as chemical stability is good, high temperature resistant, corrosion-resistant, be widely used, but also there is fatal shortcoming in this class crucible, and be exactly that plasticity and toughness are poor, fragility is big, and thermal shock resistance is low.Traditional sidewall of crucible is an one, because to produce stress concentrated the expand with heat and contract with cold end that acts on crucible and wall junction, crackle occur even bursts in temperature-rise period, has a strong impact on the service life of crucible.
Summary of the invention
This practical purpose is the deficiency that exists at above-mentioned prior art, provides a kind of and can effectively avoid in the heating-cooling process, owing to expand with heat and contract with cold, the stress of generation is concentrated the high-temperature ceramic copple that causes crucible to destroy.
The utility model purpose is achieved through the following technical solutions.
A kind of high-temperature ceramic copple, it is characterized in that: this crucible respectively by at the bottom of crucible loam cake, the crucible, the crucible wall body forms, wherein: have boss below the crucible loam cake, the upper surface has boss at the bottom of the crucible, and sidewall of crucible inwall upper/lower terminal has respectively and boss external diameter at the bottom of crucible loam cake, the crucible and interior ledge structure highly identical and that the gap embedding cooperates.
Bossing embeds the crucible wall body at the bottom of crucible cover and the crucible, and it is external along size that the outside dimensions of crucible cover can be a bit larger tham crucible.The crucible circle is a hollow cylinder or square, in order to increase gas permeability, can separate several passages in sidewall of crucible upper edge portion, also can open the gas aperture on crucible cover.
The utility model is by changing the structure of crucible, adopt the new structure of false bottom, detachable cap, three parts at the bottom of crucible cover, sidewall of crucible, the crucible are combined becomes a crucible, crucible each several part in the heating-cooling process can freely be expanded with heat and contract with cold within the specific limits, avoid or reduce stress concentrating the crucible that causes to destroy, thereby improved the heat resistanceheat resistant performance of crucible greatly, prolonged the service life of crucible.

Fig. 3 is the signal of crucible wall body.
Fig. 4 is the crucible cover schematic diagram.
Fig. 5 is a schematic diagram at the bottom of the crucible.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of high-temperature ceramic copple, this crucible respectively by at the bottom of crucible loam cake, the crucible, the crucible wall body forms, wherein: have boss below the crucible loam cake, the upper surface has boss at the bottom of the crucible, and sidewall of crucible inwall upper/lower terminal has respectively and boss external diameter at the bottom of crucible loam cake, the crucible and interior ledge structure highly identical and that the gap embedding cooperates.At first crucible cover and sidewall of crucible are fitted in together, after the material that needs to carry out under at high temperature calcining, the high temperature physical-chemical reaction is put into, cover crucible cover again and be placed on and calcine in the high temperature furnace or react.The hot anti-seismic performance of its crucible improves, and the stress of the crucible that the expanding with heat and contract with cold of intensification or cooling of having no way of causes concentrates the crucible damage phenomenon that causes to take place, and has prolonged the service life of crucible.
