Abstract
The invention discloses a kind of method that protection cubic boron nitride synthesizes post; by making a rustless steel cylinder carrying hermatic door; and the cubic boron nitride synthesis cylinder of synthesis is directly placed in body of stainless steel; it is filled with body of stainless steel using noble gases simultaneously, and seals body of stainless steel, make cubic boron nitride synthesize column sealing protection; not only can protect for a long time; in feeding, only body of stainless steel hermatic door need to be opened, simple and practical.
Description
Technical field
The invention belongs to superhard material synthesis technical field, more particularly, to a kind of side of protection cubic boron nitride synthesis post
Method.
Background technology
In the prior art, existing cubic boron nitride（CBN）It is typically with hexagonal boron nitride（hBN）For raw material in catalyst
Through the synthesis of High Temperature High Pressure process under participation, and synthetic catalyst adopts alkali metal or alkaline-earth metal and their nitridation mostly
Thing.These catalyst more active in atmosphere it is easy to react, at it with the oxygen of in the air, water vapour, carbon dioxide
Surface forms one layer of oxide or carbonate, and these oxides or carbonate, during synthesizing cubic boron nitride, hinder cube
Boron nitride crystal nucleation, carbonate even discharges carbon dioxide at high temperature under high pressure, easily causes cubic hinge press synthesis
There is gas big gun in cavity, very harmful to top hammer of cubic press.Generally, after the completion of cubic boron nitride synthesis post compacting, warp
Cross Vacuum Package to be stored in polymeric seal bag, but time length is susceptible to swollen bag, cause sealing to decline.
The main defect of this sealing preserve mode is：
1st, need substantial amounts of polymeric seal bag, after having used, not reproducible use, consumed resource is big, production cost
High；
2nd, workload is big, needs personnel not to be parked in sealing, time-consuming, inefficiency on vacuum sealing machine；
3rd, the resting period is shorter, long swollen bag can occur, reduce sealing effectiveness.
Content of the invention
The invention provides it is a kind of when simplifying production technology, reduces cost, being easy to industrialization and work continuously, synthesize post and deposit
Between long and environmental protection, again can guarantee that synthesis cylinder in inert atmosphere new method, for replacing polymeric seal bag.
The technical solution used in the present invention is：A kind of method that protection cubic boron nitride synthesizes post, comprises the following steps：
The first step：Make a rustless steel cylinder, described rustless steel cylindrical member at one end sealing, one end carry the close of rubber bar
Seal up a door, the valvular air inlet of both sides band and gas outlet and pressure gauge；
Second step：The cubic boron nitride synthesis cylinder of synthesis is directly placed in body of stainless steel, one end is carried rubber bar and seals
Door uses screwed screw tightening；
3rd step：Close air inlet valve, vacuum pump bleeding point is accessed gas outlet, opens valve, arrived with vacuum pump pumping 3
5min simultaneously closes body of stainless steel valve；
4th step：The air inlet of the body of stainless steel that argon bottle or nitrogen cylinder access are deposited, pours nitrogen or argon, is inflated to not
For, till malleation, closing argon or nitrogen bottle valve inside rust steel body, finally close body of stainless steel air inlet valve.
The beneficial effect comprise that：The present invention utilizes stainless good sealing property, now closes cubic boron nitride
Air that Cheng Zhuzhong has etc. is taken out, and inside no or during very little air, is being filled with noble gases, is being fully sealed guarantor
Shield, not only can protect for a long time, due to the pressure inside body of stainless steel is changed into malleation, during feeding, only need to be by body of stainless steel
Hermatic door is opened,Simple and practical.
The method that the protection cubic boron nitride of the present invention synthesizes cylinder, compared with traditional vacuum Polythene Bag sealing, no
Cubic boron nitride synthesis cylinder only can be stored for a long time, body of stainless steel can be reused simultaneously, and operation sequence is simple, raw
Producing efficiency high, being easy to large-scale industrial production, thus greatly reducing production cost.
Specific embodiment
Below by way of two embodiments, technical scheme to be described.
Embodiment one：
Make a kind of rustless steel cylinder, the cylindrical one end of rustless steel seals, the other end is provided with the hermatic door with rubber bar, no
The rust cylindrical both sides of steel also carry valvular air inlet and gas outlet and pressure gauge.It is first turned on body of stainless steel hermatic door, stand
Square synthesis of BN cylinder is put in body of stainless steel, and one end is carried the rubber screwed screw tightening of bar hermatic door.Close
Close air inlet valve, vacuum pump bleeding point is accessed gas outlet, opens valve, be evacuated 5min with vacuum pump.Close body of stainless steel
Valve.Argon bottle is accessed the air inlet of body of stainless steel deposited, pours argon, be inflated to and inside body of stainless steel for malleation be
Only, close argon bottle valve, finally close body of stainless steel air inlet valve.
Embodiment two：
Make a kind of rustless steel cylinder, the cylindrical one end of rustless steel seals, the other end is provided with the hermatic door with rubber bar, no
The rust cylindrical both sides of steel also carry valvular air inlet and gas outlet and pressure gauge.It is first turned on body of stainless steel hermatic door, stand
Square synthesis of BN cylinder is put in body of stainless steel, and one end is carried the rubber screwed screw tightening of bar hermatic door.Close
Close air inlet valve, vacuum pump bleeding point is accessed gas outlet, opens valve, be evacuated 4min with vacuum pump.Close body of stainless steel
Valve.Nitrogen cylinder is accessed the air inlet of body of stainless steel deposited, pours nitrogen, be inflated to and inside body of stainless steel for malleation be
Only, close nitrogen bottle valve, finally close body of stainless steel air inlet valve.
