High-temperature and high-pressure artificial diamond cultivation bin

The invention relates to the technical field of diamond production, in particular to a high-temperature and high-pressure artificial diamond cultivation bin, which gathers carbon elements infiltrated in a solvent ring to the vicinity of a diamond seed crystal, improves the synthesis speed and reduces the production cost. Comprising a pyrophyllite block with a columnar cavity, the middle of the cavity of the pyrophyllite block is sequentially sleeved with a dolomite tube, a carbon tube and a magnesium cup from outside to inside, and two ports of the pyrophyllite block are sequentially sleeved with pyrophyllite rings, dolomite rings and conductive steel sheets from outside to inside in the radial direction; the two pieces of carbon paper are located at the upper end and the lower end of the carbon tube and the magnesium cup and between the two dolomite rings respectively, a heat preservation piece, a carbon source piece, a first solvent ring, a concentration ring, a crystal bed and a heat preservation piece are
