Abstract
The utility model discloses a device for synthesizing artificial diamond or cubic boron nitride, particularly a superhigh pressure and high temperature chamber for superhard material. A cylinder-shaped through hole is arranged at the cube centre, and the middle part of the through hole is provided with a liner which is provided with a metal lining layer. When the utility model is used, metal sheets are installed at the two ends of the liner, and an electric conduction lid is installed outside the liner. The distribution gradient of the high temperature field in the high temperature chamber is extremely small, the metal lining layer shielding prevents the pollution to the material, so that the saw blade stage content of the product is greatly increased and the intensity is high. Meanwhile, contact area of the top hammer and the electric conduction lid is enlarged, the consumption of the top hammer is obviously reduced, and the economical benefit is obviously increased.
Description
The utility model relates to electric heater unit, particularly in order to the high pressure high temperature chamber of superhard materials such as synthesis of artificial diamond or cubic boron nitride.
Diamond is synthetic under high pressure high temperature, commercially available industrial diamond mostly adopts static pressure method to make, said static pressure method is that the hexahedron high pressure high temperature chamber that the pyrophyllite material is made is placed cubic hinge press, makes based on the material of graphite by the heating of heavy current high temperature.The outdoor shape of used hexahedron high pressure high temperature is six squares, and the center is an axis hole shape supplies room, and convex shoulder shape is formed on the supplies room bottom, as shown in Figure 2, places conductive cap 7 in the electric cap hole 15 at convex shoulder place.Add a cover the sealing ring 16 that materials such as pyrophyllite are made at an upper portion thereof, the conductive cap 14 of packing in the hole of sealing ring after inserting material in the supplies room 4 at hot room 1 center.Said conductive cap is to fill up the pyrophyllite material to make in bottle cap shape metallic sheath.This hot room is produced in diamond or the cubic boron nitride at super-pressure and is had the big problem of high-temperature field distribution gradient, the electric current that is added on the conductive cap is concentrated to the material center when annular cap body enters in the material, separately flow to the ring cap body of this conductive cap during to other end conductive cap again, cause Temperature Distribution irregular; In addition, material contacts with master side's body, and there is pollution in the contained trace element in high pressure high temperature chamber itself to the diamond growth course.Therefore, with the synthetic diamond in existing high pressure high temperature chamber, its trade mark is MBD8, SMD, granularity be 50/60 and thick saw blade level content only between the 18-23%.Because conductive cap and hard alloy top hammer contact area are little, the top hammer damages easily in addition, and the hard alloy top hammer of every myriagram particle diamond causes the product cost height between consuming 20 to 25 kilograms, and economic benefit is not good.
The purpose of this utility model is to provide a kind of novel synthesizing superhard material to use the high pressure high temperature chamber, by improving the shape and structure of high pressure high temperature chamber, to improve synthetic diamond saw blade level content by a relatively large margin, reduce hard alloy top hammer consumption, product cost is had by a relatively large margin descend, to improve the economic benefit in the industrial production.
The purpose of this utility model is achieved by the following scheme: at the cube center cylindrical hole is set, the lining of being made by high temperature insulation materials such as alkali halogen, talcum, pyrophillite, dolomites is installed in middle part at through hole, and the inwall of lining is provided with metal lining; This high pressure high temperature chamber also is provided with sheet metal and the conductive cap that is loaded on the lining two ends and mates with through hole.
Use the synthetic synthesizing superhard material high pressure high temperature chamber production exceptional hardness material (diamond or cubic boron nitride) of the utility model, (the former conductive cap of going up is loaded in the sealing ring because of the conductive cap area at two ends strengthens, this novel conductive cap is identical with former sealing ring diameter), strengthen with the hard alloy top hammer contact area, thereby alleviated top hammer impaired possibility under high pressure-temperature, reduced spoilage, the hard alloy top hammer consumption rate can be reduced to average every myriagram and be drawn below 15 kilograms, this high pressure high temperature chamber is in high pressure-temperature control, electric current is via an end conductive cap, to partly overlapping the end sheet metal.Again in lining metal lining and material (graphite), hold sheet metal to arrive in addition to hold conductive cap in addition, to form the electrical heating field, its CURRENT DISTRIBUTION is even, forms evenly electric heating field.Lining plays insulation effect again in addition, and the sealed environment that metal lining and two ends sheet metal form can avoid the trace element of hot room to pollute.Therefore, can improve the synthetic ratio of high-quality Buddha's warrior attendant, its MBD8, SMD trade mark granularity be 50/60 and thick saw blade level content can bring up to more than 35% and intensity height.Because the reduction of top hammer consumption, product cost can reduce about 15%, and remarkable in economical benefits increases.
Be described further below in conjunction with accompanying drawing

Fig. 2 is original hot room structural representation
As shown in Figure 1, this high pressure high temperature chamber is to be provided with cylindrical hole at the center of cube 1, and the through hole middle part is provided with lining 2, and the inwall of lining is provided with metal lining 3, is supplies room 4 in the metal lining; Behind the material of packing into, two ends cover with sheet metal 8,13, and the conductive cap 7,14 of packing at the through hole two ends at last also is the inner that sheet metal is loaded on conductive cap, and the diameter of above-mentioned sheet metal and conductive cap should mate with cubical through hole; In order further to improve the temperature field in the supplies room, improve the growth of diamond effect, can be provided with by graphite and AL203, alkali halogen or quartz sand and not be phase-changed into micro-phase transformation under HTHP, having increases the heating plate 6,11 that the resistive performance material is made, and this heating plate is disc; Sealing ring 9,12 internal diameters and heating plate coupling, cylindrical and cube through hole coupling.In use, the sheet metal 5,10 of packing at lining 2 two ends earlier, this sheet metal is identical with the sheet metal external diameter of conductive cap the inner, and then puts into sealing ring and heating plate.The sheet metal of conductive cap and the inner thereof is outside heating plate.
