Abstract
The utility model relates to a seamless platinum crucible, the cross -section of crucible is rectangle cavity thin wall, the crucible top is uncovered, bottom welding seal form a seamless body structure and the inside inner chamber that forms the cuboid of crucible, its inner wall is levelly and smoothly smooth, the whole annealing process of crucible. Adopt the platinum material of high -purity, cooperate the seamless cuboid inner chamber of its inner wall, offer excellent environment of crystal growth, the thermodynamics characteristic of the consideration crystal in the aspect of its size of on the other hand and the structural characteristic of final products, the growth container of having solved synthetic mica super large single crystal produces the lou technical problem of crucible easily.
Description
Technical field
This utility model relates to a kind of seamless platinum crucible.
Background technology
At present, artificial mica synthesis oversized single crystal is the crystalline material of growth in the platinum crucible of special requirement.
This material belongs to silicate mineral, and under high temperature (1500 DEG C) molten condition, corrosivity is extremely strong, thus necessary
With platinum crucible as the growing container of crystal.But owing to its thermal requirements is the highest with material requirements, big and
The crucible of thin-walled (thickness 0.09mm), due to the defect in its technique and product design, when welding, pole holds
Duck eye and sand holes easily occur, small sand holes are difficult to find, it is easy to cause leakage crucible, affect crystal mass,
Even produce waste product, there is no a kind of product so far and can avoid the problems referred to above completely, so needing badly a kind of seamless
Platinum crucible, the growing container solving artificial mica synthesis oversized single crystal easily produces the technical problem of Lou crucible.
Summary of the invention
The purpose of this utility model is to provide a kind of seamless platinum crucible, solves artificial mica synthesis super large list
Brilliant growing container easily produces the technical problem of Lou crucible.
The technical scheme that this utility model employing is following:
A kind of seamless platinum crucible, described crucible is hollow, seamless thin ring cylinder, and its cross section is rectangle, institute
Stating crucible top is uncovered (1), and bottom welded closure forms rectangular structure and is internally formed length at described crucible
The inner chamber of cube, its inwall flat smooth, the overall annealed process of described platinum crucible.
The wall thickness of described thin ring cylinder is 0.08 to 0.1mm, a length of 140mm of described crucible, a width of 22mm, height
For 350mm.
Described seamless platinum crucible is platinum material, and its purity is 99.95%.
Advantage of the present utility model is as follows:
1. use highly purified platinum material, coordinate the cuboid inner chamber of wall seamless in it, it is provided that to crystal growth one
Individual excellent environment, it is to avoid leakage crucible, improves crystal mass；On the other hand the consideration in terms of its size
The thermodynamic behaviour of crystal and the architectural characteristic of final products.
2. the internal premise grown up for crystal orientation smooth, smooth of crucible.The overall annealed processing intent of described crucible
Being to make sidewall of crucible soft, with crystal seed and expect the smooth of block docile, discount is tight.
Accompanying drawing illustrates:
Fig. 1 is internal broken section structural representation of the present utility model；
Fig. 2 is process chart of the present utility model；
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further.
Following example are only for understanding explanation this utility model example, and not to this utility model
The restriction of embodiment.For those of ordinary skill in the field, on the basis of the following description
Change or the variation of other multi-forms can also be made, and these belong to what this utility model spirit was drawn
Obviously change or change among still in protection domain of the present utility model.
A kind of seamless platinum crucible, described crucible is hollow, seamless thin ring cylinder, and its cross section is rectangle, institute
Stating crucible top is uncovered 1, and bottom welded closure forms rectangular structure and is internally formed rectangular at described crucible
The inner chamber of body, its inwall flat smooth, the overall annealed process of described platinum crucible.
The wall thickness of described thin ring cylinder is 0.08 to 0.1mm, a length of 140mm of described crucible, a width of 22mm, height
For 350mm.
Described seamless platinum crucible is platinum material, and its purity is 99.95%.
Its manufacturing process is:
(1) take appropriate platinum and put into the silica crucible melted (about 2000 DEG C) of intermediate frequency furnace.
(2) melted platinum is cast material ingot ring.
(3) forge into the material ingot ring of suitable diameter, coordinate suitable mold.
(4) it is rolled into thin-walled ring, thickness 0.08～0.1mm with lathe, reaches change mold the most again and roll
Wheel so that it is reach preferable diameter.
(5) being converted into flat tubular, has one's hair trimmed sizing (22 × 140 × 350mm) in two ends.
(6) one end oxyhydrogen welding is sealed, the other end integrally annealed.
Specifically used method:
Platinum crucible is placed in special mould, is initially charged with material block 21.5 × 139 × 223mm mono-piece, refills
Enter 21.5 × 139 × 100mm crystal seed one piece of book-like arrangement, notice that the corner angle avoiding expecting ingot and crystal seed scratch platinum
Crucible.Preventing melt from flowing down, crucible top is smooth, the most concavo-convex fluctuating, it is ensured that the plane of crystal obtained
Smooth and have enough length, and prevent thermal stress from concentrating, then uncovered folding is sealed, during use, revolved
Turn in being inverted and be positioned over the refractory tube of growth furnace and use.
