GBF-1700-RHP4 is a rapid hot press (RHP) in a glovebox with a fast cooling function. The sample is inductively heated at ~ 1°C/ second up to 1600°C and pressed to Max. 100 MPa using a 5-ton electric press. Then, the sample and graphite die are quickly cooled by two water-cooled copper clamps by direct contact with a cooling speed up to 10°C/s
