Abstract

The present invention relates to synthesis process of artificial diamond, and aims at raising the yield and quality of artificial diamond. The synthesis process includes assembling material including catalyst, carbon sheets and pyrauxite; stoving at 130-140 deg.c, and synthesis with the technological parameters including heating pressure 80 MPa, middle stop pressure 88 MPa and time 40 sec, maintaining pressure 100 MPa and synthesis power 70. The said process can obtain yield of 39 carat each time, and the product has component of strength over 13 Kg of about 30 %.

Description

The synthetic method of man-made diamond
Technical field: the synthetic method that the present invention relates to a kind of man-made diamond.
Background technology: at present artificially synthesizing diamond all is to be raw material with catalyst, carbon plate, agalmatolite piece, they are fitted together, toast in 130-140 ℃ of temperature, the synthetic processing parameter is: send warm 40MP, in stop 70MP, pressurize 99.5MP, synthetic power 80, between the middle stopping time 40 seconds.Shortcoming is to yield poorly, 35.5 carats of per unit area yields, and quality percentage is low, and ratio is about 25% more than intensity 〉=13 kilogram.
Summary of the invention: the objective of the invention is to study a kind of synthetic method that can improve the high man-made diamond of diamond output and quality percentage.
The object of the present invention is achieved like this: catalyst, carbon plate, agalmatolite piece are fitted together, toast in 130--140 ℃ of temperature, our synthesis technologic parameter is: send warm 80MP, in stop 88MP, pressurize 100MP, synthetic power 70, between the middle stopping time 40 seconds.
Advantage of the present invention is the output height, 39 carats of per unit area yields, and the quality percentage height, ratio is about 30% more than intensity 〉=13 kilogram.
Embodiment: catalyst, carbon plate, agalmatolite piece are fitted together, toast in 130-140 ℃ of temperature, the synthetic processing parameter is: send warm 80MP, in stop 88MP, pressurize 100MP, synthetic power 70, between the middle stopping time 40 seconds.
