Description

Technical Field

[0001] The utility model relates to the field of cubic boron nitride processing equipment, in particular to a cubic boron nitride powder purification treatment device. Background Art

[0002] Cubic boron nitride polycrystals are formed by sintering cubic boron nitride powder under high temperature and high pressure in the presence of a binder. In order to ensure the quality of cubic boron nitride polycrystals, the cubic boron nitride powder needs to be purified to remove internal impurities. When purifying traditional cubic boron nitride powder, it needs to be boiled in a strong acid mixture, washed with distilled water, and dried. Purification operations must be performed multiple times to ensure the purification effect of the cubic boron nitride powder. However, there is no stirring device during the heating and distillation process of the boron nitride powder, which causes the boron nitride powder to be heated unevenly when boiled with the strong acid mixture, increasing the boiling and distillation time. After the stirring device stirs the material, if the stirring device is left in the material to be boiled, the strong acid and high temperature substances will damage the stirring device, reducing the service life of the stirring device.
