ABSTRACT:
A cell adapted for producing high temperatures and high pressures comprising a three-layered box.
The inner layer is made of an electrically insulating material, the intermediate layer is made of a conductive material and the outer layer is made of an electrically and thermally insulating material. An electric current is permitted to flow through the conductive intermediate layer via electric contacts disposed in the outer layer to heat samples in the sealed chamber.
Gaskets, mounted outside the cell for sealing high pressure in the cell, are prevented from being heated whereby a high pressure sealing effect is maintained effectively even though the cell is heated at a high temperature.
