Abstract
The utility model discloses a PBN crucible unable adjustment base for single crystal preparation in -process, PBN crucible unable adjustment base includes the base base member, the base base member be around two sides four parallel terrace with edges, the up end of base base member be the identical ARC groove with PBN crucible shape of bottom face, the diameter of ARC groove cross -section arc place circle is the same with the external diameter of PBN crucible, the width of base base member slightly is greater than the diameter of crucible, 34, the ARC groove concave surface that the length of base base member be the partial length of PBN crucible constant diameter passes through with the side one -tenth fillet of base base member. PBN crucible unable adjustment base goes on fixedly effectively to the PBN crucible, reduction stress reduces the wearing and tearing of methyl alcohol stove to the PBN crucible to the damage of PBN crucible to the life of extension PBN crucible saves manufacturing cost.
Description
Technical field:
The utility model relates to prepares crystal technology field, is specifically related to a kind of for the PBN crucible firm banking in single crystal preparation process.
Background technology:
PBN, i.e. pyrolitic boron nitride, form hexagonal boron nitride layer by boron atom and nitrogen-atoms, together with layer is deposited in layer, there is good flexural strength, higher ultimate compression strength, higher rupture resistance, under hot conditions, mechanical property strengthens, nontoxic, do not react with other acid, alkali, organism, molten metal or graphite, therefore PBN crucible is widely used as the reaction vessel of single crystal growing.
In raw material thawing and single crystal growth process, melt and crucible Long contact time can produce adhesion phenomenon.After single crystal growing, need to carry out demoulding process, open by the crystal separation in PBN crucible and crucible.The operating process of the demoulding is: PBN crucible is kept flat the methanol stove into constant temperature, and whole crucible is fully immersed in methyl alcohol, until crystal can be separated completely with crucible.Due to a kind of stupalith goods of PBN crucible, easily occur crackle, in knockout course, PBN crucible can have direct contact with methyl alcohol groove, therefore may cause damage in various degree to PBN crucible.
Utility model content:
In order to solve the problems of the technologies described above, the utility model proposes a kind of for the PBN crucible firm banking in single crystal preparation process, PBN crucible firm banking is fixed effectively to PBN crucible, reduce stress to the damage of PBN crucible, reduce methanol stove to the wearing and tearing of PBN crucible, thus extend the work-ing life of PBN crucible, save production cost.
The technical solution of the utility model is: a kind ofly comprise base matrix for the PBN crucible firm banking in single crystal preparation process, described base matrix is the parallel truncated rectangular pyramids in two sides, front and back, the upper surface of base matrix is the cambered surface groove matched with PBN crucible bottom shape, cambered surface channel section arc place circular diameter is identical with the external diameter of PBN crucible, the width of base matrix is slightly larger than the diameter of crucible, the length of base matrix is 3/4 of PBN crucible equal-diameter part length, and cambered surface groove concave surface becomes round-corner transition with the side of base matrix.
The utility model has following beneficial effect: 1, basis is novel can effectively fix PBN crucible, prevents PBN crucible from moving in methanol stove groove; 2, Absorbable organic halogens, snugly hold PBN crucible, reduce stress to the damage of PBN crucible; 3, avoid the contact of PBN crucible and methyl alcohol groove, reduce methyl alcohol groove to the wearing and tearing of PBN crucible, thus extend the work-ing life of PBN crucible, save production cost.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is vertical views of accompanying drawing 1.
In figure: 1-base matrix; 2-cambered surface groove; 3-fillet.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind ofly comprise base matrix 1 for the PBN crucible firm banking in single crystal preparation process, described base matrix 1 is the parallel truncated rectangular pyramids in two sides, front and back, the upper surface of base matrix 1 is the cambered surface groove 2 matched with PBN crucible bottom shape, cambered surface groove 2 internal surface is smooth, arc place, cambered surface groove 2 cross section circular diameter is identical with the external diameter of PBN crucible, the width of base matrix 1 is slightly larger than the diameter of crucible, while avoiding base to take too much space, guarantee to there is certain interval between adjacent PBN crucible, effectively prevent the mutual scratch between PBN crucible, the length of base matrix 1 is 3/4 of PBN crucible equal-diameter part length, guarantee PBN crucible Absorbable organic halogens, be fixed on evenly on base, cambered surface groove 2 concave surface becomes fillet 3 transition with the side of base matrix 1.
In actually operating; PBN crucible is positioned on cambered surface groove 2; because arc place, cambered surface groove surface 2 cross section circular diameter is identical with the external diameter of PBN crucible; so cambered surface groove 2 and crucible outer wall can be fitted completely; thus the effective effect supporting and protect can be reached to PBN crucible, reduce stress to the damage of PBN crucible.PBN crucible can be fixed in methyl alcohol groove by base matrix 1 effectively, and fillet 3 can avoid base to the damage of PBN crucible.
