The integral manufacturing of sour yttrium crystal require it is relatively high, especially its cutting or later period it is selected during, only merely
Carry out post-processing the problem of it is sorted, will lead to crystal bulk quality, leading to itself, have the effect of, receives shadow
It rings, or during post-production, occurs processing not exquisite, excessively simple, part is caused defect occur.
Innovation and creation content
The purpose of the invention is to provide a kind of yttrium vanadate crystal thin slice production technology.
The above-mentioned technical purpose of the invention has the technical scheme that
A kind of yttrium vanadate crystal thin slice production technology, which is characterized in that including Yttrium Orthovanadate (YVO4) crystal growth, by ammonium metavanadate
(NH4VO3) solution is dissolved, and is purified by high temperature, and then yttrium oxide (Y2O3) is carried out by nitrous acid (HNO2)
Mixed dissolution is then put into Yttrium Orthovanadate (YVO4) crystal and is precipitated, and the process that reacts is added ammonium hydroxide and generates oxalic acid, then
By separation of solid and liquid, centrifugation, washing and drying, then Yttrium Orthovanadate (YVO4) crystal after refined filtration by throwing, orienting in advance
And cutting, before three be repeated after operation three times, carry out in inspection, by Yttrium Orthovanadate (YVO4) crystal of interior inspection again into
After twice corase grinding repeatedly and essence throw, reach and pass through essence inspection and plated film after requirement, by finally carrying out finished product packing, third
Preceding Yttrium Orthovanadate (YVO4) crystal by after cutting is directly simplified, directly into plated film and packing.
Preferably, temperature passes through heating at 4-5 between 1000-1250 ° to heating in mixed liquor
Between hour.
Preferably, being polished using the Yttrium Orthovanadate (YVO4) polishing crystal machine to plane of crystal, Yttrium Orthovanadate (YVO4)
Crystal, which is placed on glass slide, is placed on device side, is oriented by X-ray positioner, again by diamond dresser
Carry out corase grinding and rough polishing, it is desirable that in profile control less than 0.25 λ, while the depth of parallelism is less than 0.05mm.
Preferably, carrying out smart throwing to the surface of Yttrium Orthovanadate (YVO4) crystal, together further by single side polishing machine machine
When chip the long Yttrium Orthovanadate of lower shaft (YVO4) crystal reconditioning bottom sides and side top, while the required precision after reconditioning is small
In 6 points.
Preferably, controlling the pH value of liquid during Yttrium Orthovanadate (YVO4) crystal production between 7.5-8.
Preferably, the addition proportion of the ammonium metavanadate (NH4VO3) and yttrium oxide (Y2O3) is 3 parts: 5 parts.
Detailed description of the invention
Fig. 1 is the invention device flow diagram.
Specific embodiment
As described below is only the preferred embodiment of the invention, and protection scope is not limited merely to the embodiment, all
The protection scope of the invention should belong in the technical solution belonged under the invention thinking.Simultaneously it should be pointed out that for
For those skilled in the art, several improvements and modifications under the premise of not departing from the invention principle, this
A little improvements and modifications also should be regarded as the protection scope of the invention.
As shown in Figure 1, a kind of yttrium vanadate crystal thin slice production technology, which is characterized in that including Yttrium Orthovanadate (YVO4) crystal
Growth, ammonium metavanadate (NH4VO3) solution is dissolved, the addition proportion of ammonium metavanadate (NH4VO3) and yttrium oxide (Y2O3)
It is 3 parts: 5 parts, is purified by high temperature, to heating in mixed liquor, temperature passes through and adds between 1000-1250 °
Yttrium oxide (Y2O3) is then carried out mixed dissolution by nitrous acid (HNO2), then Yttrium Orthovanadate between 4-5 hour by temperature
(YVO4) crystal, which is put into, is precipitated, and the process that reacts is added ammonium hydroxide and generates oxalic acid as YVO4 during reacting
Solution concentration is higher, just will appear the hydrate of V2O5 when pH value is close to 2 or so, acid is added further at this time, this is heavy
Form sediment again can the yttrium vfanadium compound that is generated under different pH values of dissolution vanadate again it is different, so needing to control well
The pH value of the solution is made, because controlling the pH value of liquid during Yttrium Orthovanadate (YVO4) crystal production between 7.5-8.
As shown in Figure 1, being polished using Yttrium Orthovanadate (YVO4) polishing crystal machine to plane of crystal, Yttrium Orthovanadate (YVO4) crystal
It is placed on glass slide and is placed on device side, be oriented by X-ray positioner, carried out again by diamond dresser
Corase grinding and rough polishing, it is desirable that in profile control less than 0.25 λ, while the depth of parallelism is less than 0.05mm, then by being separated by solid-liquid separation, from
The heart, washing and drying, then Yttrium Orthovanadate (YVO4) crystal after refined filtration by throwing, orienting in advance and cutting, before three
It is repeated after operation three times, carries out interior inspection, specific process is to be located at first by the process and then secondary adjustment thrown in advance
Crystal on slide glass, is then polished again, then again by orientation, when biggish deviation occurs in part, by cutting
The mode cut carries out adjustment again to it and is thrown in advance again at this time, takes out the crystal thrown in advance at this time and passes through interior inspection, detection
The preliminary situation of crystal.
As shown in Figure 1, Yttrium Orthovanadate (YVO4) crystal by interior inspection is thrown into after corase grinding repeatedly twice with essence again, reach
It is required that after by essence inspection and plated film, by finally carrying out finished product packing, third before by cutting after Yttrium Orthovanadate
(YVO4) crystal is directly simplified, directly into plated film and packing, further by single side polishing machine machine, to Yttrium Orthovanadate
(YVO4) surface of crystal carries out smart throwing, while the reconditioning bottom sides of the long Yttrium Orthovanadate of lower shaft (YVO4) crystal of chip and side
There is deviation and then secondary by corase grinding in top, while the required precision after reconditioning is less than 6 points, crystal after interior inspection
Mode is adjusted, and is examined in corase grinding and then secondary progress for the first time, after its qualification, crystal is carried out smart throwing again, passed through
Crystal after essence is thrown needs to carry out smart inspection again, and the crystal after essence is thrown passes through essence inspection, by later on the surface of crystal
Plated film is carried out, after initially by cutting, can also directly carry out smart inspection, if can also can directly be plated by essence inspection
Film, last Europe finished product inspection, passes through rear storage.
