The remains are placed into a graphite crucible, and the crucible is placed into one of the machines, which uses extreme pressure and heat to simulate the process that a natural diamond goes ...

When mixed together, the two powders are heated in a graphite crucible using an arc welder with a carbon electrode. The crucible appears to be made from an EDM electrode; we’ve seen them used ...

Noltina ‘s Grafit crucibles are rib formed CLAY-GRAPHITE crucibles characterised by high refractoriness and good thermal conductivity as well as very good thermal shock resistance and chemical ...

Scientists in China have made a significant breakthrough in graphite purification. They have achieved a graphite purity level ...

The team ordered some graphite crucibles of a few sizes from a large online bookstore and started 3D printing some molds for crucible holders. They started with a smaller version to try the method.

When made by the so-called crucible method, in which an amount not over 100 pounds is melted in a graphite crucible, a high grade product is obtained, but the cost is necessarily high. By the ...

Vacuum induction melting (VIM) uses an induction heating source within a sealed, air-evacuated chamber. Often, crucibles that minimize contamination are used, and combined with the sealed chamber ...

Located just over 30 miles north of Nome, the Graphite Creek property is believed to be one of the largest known graphite deposits in the world. The entire deposit spans about 10 miles along the ...
