In one embodiment of the present invention, an assembly for HPHT processing comprises a can with an opening. A powder mixture is disposed within the opening. A substrate is disposed within the opening adjacent the powder mixture. Paint is coated on a surface within the opening and opposite the powder mixture with respect to the substrate. A meltable sealant is disposed within the opening and opposite the substrate with respect to the surface and a cap is covering the opening. In another embodiment of the present invention, an assembly for HPHT processing comprises a can with an opening, a powder mixture is disposed within the opening, a substrate disposed within the opening adjacent and above the powder mixture, a formable sealant barrier is disposed within the opening above the substrate, a meltable sealant is disposed within the opening above the formable sealant barrier, and a cap covers the opening.
A method of preparing an assembly for HPHT processing, comprising:
The method of claim 12, wherein the heating is performed in a vacuum.
The method of claim 12, wherein the further heating is performed in an inert gas.
The method of claim 12, wherein the assembly is brought to a pressure higher than atmospheric pressure.
The method of claim 15, comprising bringing the assembly back to atmospheric pressure at a temperature sufficient to melt the sealant.
The method of claim 12, wherein the cleansing temperature is between 800° C. and 1050° C.
The method of claim 12, wherein the sealing temperature is between 1000° C. and 1200° C.
The method of claim 12, wherein the first period of time is between 15 minutes and 60 minutes.
The method of claim 12, wherein the second period of time is between 2 minutes and 25 minutes.
