Abstract
The utility model relates to a sintered sapphire material with a blocky material, wherein the blocky material is added into the sintered material, chemical elements of the blocky material are the same as those of the sintered material; the blocky material is of a cuboid shape with the lengths of three sides respectively being A, B and C; the length A of the blocky material is 10-20mm, the length B of the blocky material is 15-20mm, and the length C of the blocky material is 100-200mm. According to the sintered sapphire material with the blocky material, the blocky material of a certain shape is added into an existing sintered material, the blocky material is combined with an existing pulling process to improve the growth striation of sapphire monocrystals and remove the internal stress, the sapphire is crystal clear, the growth quality is high, the sintered sapphire material with the blocky material satisfies the actual use demand in various fields, and the practical effect is good.
Description
Technical field
The utility model relates to a kind of sapphire sintered material, and especially a kind of sapphire sintered material with block material is mainly used in the growth of sapphire sintering.
Background technology
Sapphire mineral name is corundum, belongs to corundum family mineral.In fact the Gem Grade corundum of occurring in nature, except being called ruby of redness, all the other shades of colours as blue, light blue, green, yellow, grey, colourless etc., all are called sapphire.Sapphire main chemical compositions is aluminium sesquioxide (AL
2O
3).Sapphire crystal has fusing point high (more than 2000 ℃), large (9 grades of the Mohs' hardness of hardness, be only second to diamond) and good optics and physicochemical characteristic, be the very important base mateiral of microelectronics and photoelectronic industry, be widely used in the various fields such as semi-conductor, microelectronics, photoelectron, information demonstration, optical communication, laser, precision optical machinery, national defense and military and major scientific projects.
Under lab can be easy to and produce the sapphire of Gem Grade cheaply, its chemical composition is identical with natural sapphire with physical properties.The diagnostic characteristics of synthetic sapphire is the striation of crystal, and in crystal growing process rapidly, due to pulling growth, it is normally crooked.
Existing sapphire growth is mainly that sintered material is placed in the crucible of special materials (as miramint, pottery etc.), and crucible is placed in sintering oven, is constantly grown by sintered material, and finally forms a jewel single crystal.The chemical composition of sintered material is aluminium sesquioxide (AL
2O
3).Add chemical dopant in sintered material, can also produce like this sapphire of other colors that versicolor sapphire and other had not occurred at occurring in nature.
But, in existing production process, 100% sintered material sintering out after, the sapphire internal stress is larger, sapphire purity and quality are not high yet, because its internal stress is excessive, when when cutting, sapphire is easily cracked.These have all limited the application of sapphire in some fields.
The utility model content
The deficiency that the utility model exists for prior art just provides a kind of sapphire sintered material with block material.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows:
A kind of sapphire sintered material with block material adds block material in sintered material, block material is identical with the sintered material chemical composition, described block material be shaped as rectangular parallelepiped, the length on its three limit is respectively A, B, C, the length of side A scope of block material is 10mm ~ 20mm; The length of side B scope of block material is 15mm ~ 20mm; The length dimension C scope of block material is 100mm ~ 200mm.
As improvement of the technical scheme, the length of side A of described block material is 15mm or 16mm.
As improvement of the technical scheme, the length of side B of described block material is 15mm or 18mm.
As improvement of the technical scheme, the length dimension C of described block material is 130mm or 150mm.
The utility model compared with prior art, implementation result of the present utility model is as follows:
A kind of sapphire sintered material with block material described in the utility model, that block material with specified shape adds in existing sintered material, utilize block material to coordinate existing czochralski process, improve the striation of sapphire monocrystal, eliminated internal stress, and sapphire is glittering and translucent, growth quality is high, satisfy the actual user demand in a plurality of fields, actual effect is good.
Description of drawings
Fig. 1 is block material structural representation described in the utility model.
Embodiment
Content of the present utility model is described below in conjunction with specific embodiments.
As shown in Figure 1, be block material structural representation described in the utility model.Add block material 1 in existing sapphire sintered material, the chemical composition of block material 1 is identical with sintered material, is aluminium sesquioxide (AL
2O
3).Block material 1 be shaped as rectangular parallelepiped, the length on its three limit is respectively A, B, C.The length of side A scope of block material 1 is 10 mm ~ 20mm, and preferred length of side A is 15mm or 16mm.The length of side B scope of block material 1 is 15 mm ~ 20mm, and preferred length of side B is 15mm or 18mm.The length dimension C scope of block material 1 is 100 mm ~ 200mm, and preferred length of side C is 130mm or 150mm.
