Abstract Key experimental studies (mainly pulse heating) aimed at obtaining the physical properties of most refractory substance — graphite in temperature range 2000–8000 K are discussed. The considered enthalpy, input (Joule) energy, thermal expansion, specific heat, and electrical resistance, as well their dependence on level applied pressure. results obtained by pulsed current heating laser compared. An abnormally high heat just before melting point is recorded under fast (during...
The results of the study zirconium nitride ceramics (0.9ZrN + 0.1ZrO2) in solid and liquid phases are presented: temperature dependences specific input energy (enthalpy), heat, heat fusion, electrical resistivity at temperatures 2000–4500 K. To measure these properties method microsecond current pulse heating was used. specimens were obtained by spark plasma sintering method. Data for phase first time. end melting 2700 ± 70 K an estimated pressure 5 MPa. A comparison with literature data is...
