Description
Technical field
The utility model relates to diamond synthesis and uses the exotic material field.
Background technology
In the artificially synthesizing diamond industrialness was produced, conversion ratio is high, cost is low was to be the target that people generally pursue forever.And in process of production, often both can not take into account simultaneously, and cost is low, and conversion ratio is lower comparatively speaking; Cost is high, and conversion ratio is higher comparatively speaking.At present, in the diamond synthesis process, for the synthetic post of graphite catalyst two kinds of conductive heater modes are arranged, a kind of is directly heating, and this can cause thermal loss, and the efficiency of heating surface is not high, causes the not high defective of diamond conversion ratio; Also have a kind of improved procedure, do conductor material with graphite tape exactly, this material conducts electricity very well, but it is bigger to take cavity volume, and the graphite heat-transfer rate is slow and resistivity is inhomogeneous, is unfavorable for improving the efficient of suitability for industrialized production.
Summary of the invention
The utility model has solved above-mentioned defective, and conversion ratio is high, cost is low, production efficiency is high.The technical scheme of taking is: a kind of siderochrome aluminium manganese band that is used for the diamond synthesis cavity body structure; The diamond synthesis cavity body structure comprises order placement insulating core 1, conducting steel ring 2, pyrophillite piece 3, core insulator 5, the synthetic post 6 of graphite catalyst of ecto-entad; It is characterized in that: in core insulator 5 outer rings, the inwall of pyrophillite piece 3 twines siderochrome aluminium manganese band 4.This make; Because siderochrome aluminium manganese band 4 is coated on the outer ring of core insulator 5; The synthetic post 6 of graphite catalyst is not directly conducted electricity; But transmit through core insulator 5 with the conduction generation heat of siderochrome aluminium manganese band 4, changed the phenomenon of synthetic post 6 conductive exothermal when diamond transforms of traditional graphite catalyst.This mode, heat conduction is even, and firing rate is fast, and the diamond rate of growth is high.
The composition mass percent of said siderochrome aluminium manganese band is: iron 40%-60%, and chromium 20%-30%, aluminium 20%-30%, manganese are surplus.Preferred value is: iron 50%-60%, and chromium 20%-25%, aluminium 20%-25%, manganese are surplus.Optimum value is: iron 55%, chromium 20%%, aluminium 20%, manganese 5%.
The proportioning of this composition has guaranteed in the atmosphere of HTHP, and siderochrome aluminium manganese band fusing point is more than 1400 ℃; And the synthesis temperature of diamond is generally below 1400 ℃; The fusing point of siderochrome aluminium manganese band is higher than adamantine synthesis temperature like this, plays the favorable conductive heating functioin, and it is temperature required that the external temperature that makes the graphite catalyst synthesize post evenly is increased to growth of diamond fast; Dwindle synthetic cavity thermograde 25-40%, and protect the synthetic purity of diamond film more.Through the application of this kind material, can improve adamantine conversion ratio 10-15%, shorten 20-30% preheating time of the synthetic post of graphite catalyst simultaneously.
The thickness of said siderochrome aluminium manganese band 4 is 0.1-0.3mm.
It is the 2-5 circle that said siderochrome aluminium manganese band 4 twines the number of turns, and the preferred number of turns is the 2-3 circle, and optimum value is 2 circles.The mode of this winding has reduced welding process, has simplified technology, and siderochrome aluminium manganese strip resistance is even relatively, has guaranteed adamantine quality; Strengthened its electric conductivity again.
The preparation method of described siderochrome aluminium manganese band: the first step, than iron 40%-60%, chromium 20%-30%, aluminium 20%-30%, manganese are that the dusty material of surplus mixes with quality; Second step, vacuum melting under 1600-1700 ℃ of temperature, casting diameter is that 80-300 millimeter, length are the alloy ingot of 300-400 millimeter; The 3rd step, hot rolling, being cold rolled to thickness again is 0. 1-0.3 millimeter; At last, be cut into siderochrome aluminium manganese band, in the diamond synthesis process as the structure conductor heating material.The siderochrome aluminium manganese band high-temperature behavior that this method is made is good, in the diamond synthesis process, conducts electricity very well, and uniform resistivity, caloric value is stable, and it is fast to conduct heat.After twined the periphery of the synthetic post of graphite catalyst, the diamond surface of formation did not have concave surface, surfacing, and conversion ratio is very high.
