Description
Technical field
The utility model relates to crucible technique field, is specially a kind of Novel graphite crucible.
Background technology
Graphite crucible has good thermal conductance and heat-resisting quantity, and in applied at elevated temperature process, thermal coefficient of expansion is little, and anxious heat, chilling are had to certain anti-strain property, and to acid, the corrosion resistance of alkaline solution is stronger, has good chemical stability.The external structure of not protecting of some graphite crucible; directly be positioned in air; from pyroreaction to quenching, cause graphite crucible body to occur slight crack, lifetime; and graphite is in air under the melting high temperature of 800～1000 ℃; oxidation rate is very large, and service life is very short, cannot meet purity and be greater than the instructions for use of crucible for 99.99% Metal Melting; unresolved the problems referred to above, we propose a kind of Novel graphite crucible.
Utility model content
The purpose of this utility model is to provide a kind of Novel graphite crucible, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of Novel graphite crucible, comprise graphite crucible body and quartzy overcoat, graphite crucible body comprises graphite matrix, CVD antioxidant coating layer and, breathable cloth, draining hole and boss, the inwall of described graphite matrix and outer wall be provided with CVD antioxidant coating layer and, outside at described CVD antioxidant coating layer is provided with breathable cloth, the outer side covers of described breathable cloth has high-temperature adhesives, the top of described graphite matrix is provided with draining hole and boss, quartzy overcoat comprises quartzy outer sleeve body, suspension ring, base and nosing, described floor installation is in the bottom of quartzy outer sleeve body, the sidewall of described quartzy outer sleeve body is provided with equally distributed three suspension ring on same diametral plane, graphite crucible body is arranged in quartzy overcoat, by the cooperation between boss and nosing, realize fixing.
Preferably, the thickness of described CVD antioxidant coating layer is 0.5mm.
Preferably, the thickness of described breathable cloth and high-temperature adhesives and be 10mm.
Preferably, the top of described quartzy outer sleeve body is provided with nosing structure.
Compared with prior art, the beneficial effects of the utility model are: this Novel graphite crucible, the inside and outside wall of graphite matrix forms anti-oxidant graphite paint by CVD technique, in the periphery of described CVD antioxidant coating layer, adopt breathable cloth to fasten, in the outside of described breathable cloth, adopt the quartzy jacket structure of high-temperature adhesives covering and graphite crucible external body, not only strengthened the non-oxidizability of graphite crucible, and made its life-span longer.
