The selection principle are as follow, 1)higher melting point; 2) higher plasticity, transformation equality and no breaking at high pressure; 3) there is the purification function on cavity body; 4) simple technology. The effects of some common metal cup materials and some assembly modes on the ultra-high pressure-high temperature sintering process have been analyzed in detail in the present paper. Some assistances can be provided to the production of superhard materials.
