A high thermal conductivity substrate is formed by making a sintered diamond composite and thereafter modifying the electrical properties of the composite by leaching graphite and other non-diamond materials from the composite and subsequently infusing the leached composite with material having known electrical properties. Alternatively, a diamond composite having high thermal conductivity known electrical properties is prepared and subsequently leached to remove graphite and other materials which interfere with the known electrical properties of the composite material.

High pressure/high temperature treatment apparatus for diamond

본 발명은 다이아몬드의 색 변화를 위한 고온고압처리에 적합한 다이아몬드 고온고압처리장치에 관한 것으로서, The present invention relates to a diamond high temperature and high pressure treatment apparatus suitable for high temperature and high pressure treatment for the color change of diamond, 다이아몬드를 그 내부에 구비한 셀과, 상기 셀을 사이에 두고 가압하는 서로 대향하는 엔빌(anvil)을 포함하여 구성되는 다이아몬드 고온고압처리장치에 있어서, 상기 엔빌은, 대향하는 셀 가압면에 오목면이 각각 형성되고, 상기 셀은, 그 상부면 및 하부면에 상기 엔빌의 오목면에 대응하는 볼록면이 각각 형성되며, 그 수평방향 길이가 수직방향 길이보다 큰 것을 특징으로 한다. In a diamond high temperature and high pressure treatment apparatus comprising a cell provided with diamond therein and an opposing anvil for pressurizing the cell therebetween, the anvil is a concave surface on an opposing cell pressing surface. Each of the cells is formed, and the convex surface corresponding to the concave surface of the anvil is formed on the upper surface and the lower surface, respectively, characterized in that the horizontal length is larger than the vertical length. 본 발명에 의하면 다이아몬드의 전표면을 고르게 가압할 수 있게 된다. According to the present invention, the entire surface of the diamond can be evenly pressed. 또한, 엔빌의 상대적인 상하간격이 종래의 장치에 비하여 작아서 인장응력성분이 대폭 감소하므로, 종래와 같은 다이나 스틸링을 셀의 측면에 설치할 필요가 없어 제조비용이 절감될 뿐만 아니라, 색변화에 요구되는 유효압력을 용이하게 유지할 수 있으며, 종래보다 더 높은 유효압력으로 다이아몬드를 가압할 수 있게 된다는 장점이 있다. In addition, since the relative vertical gap of the anvil is smaller than that of the conventional apparatus, the tensile stress component is greatly reduced. Therefore, it is not necessary to install the same dyna steel ring on the side of the cell, thereby reducing manufacturing cost and requiring color change. The effective pressure can be easily maintained, and there is an advantage in that the diamond can be pressurized with a higher effective pressure than in the prior art.

High pressure and high temperature production of diamonds

The present invention is directed to a method for treating discolored natural diamond, especially Type IIa diamond and Type IaA/B diamond with nitrogen as predominantly B centers, for improving its color. The method includes preblocking and preshaping a discolored natural diamond to prevent its breakage in a high pressure/high temperature (HP/HT) press, placing said discolored natural diamond in a pressure transmitting medium which is consolidated into a pill. Next, the pill is placed into a HP/HT press at elevated pressure and elevated temperature within the graphite-stable or diamond-stable range of the carbon phase diagram for a time sufficient to improve the color of said diamond. Finally, the diamond is recovered from said press. Colorless and fancy colored diamonds can be made by this method.

Method and apparatus for manufacturing synthetic products

A plural number of types of material powders are accommodated in an accommodation chamber in a mixed state and the material powders are continuously subjected to a self-exothermic reaction inducing chemical reactions between the material powders caused by heat of reaction released when the mixed material powders synthesize. The synthesized material of high temperature due to the self-exothermic reaction is pressed by utilizing an electromagnetic force just after the finish of the self-exothermic reaction. The exothermic reaction is caused by an ignition circuit including an ignition electrode and the electromagnetic force is generated by an electromagnetic force generation circuit including an electric current inducing means. These circuits are connected through and regulated by a relay circuit. Thus the synthetic products of fine structure are obtained.

High pressure reaction vessel for growing diamond on diamond seed and method therefor

Reaction vessel construction is described for suppressing spontaneous diamond nucleation and simultaneously reducing the flaw content in the main body of diamond grown from diamond seed material by the process broadly disclosed in U.S. Pat. No. 3,297,407 to Wentorf, Jr. In the reaction vessel construction the body of catalyst-solvent metal is formed with at least one small tip projecting from the underside thereof. A single diamond seed is placed in contact with this (or each) tip. The underside of the plug of catalyst-solvent metal is in contact with a nucleation-suppressing disc, or layer, of a material different from the catalyst-solvent and selected from a specific group of materials. In each case the tip of catalyst-solvent metal projects through a hole in the disc or layer to make contact with the diamond seed material.
