An apparatus includes a first electrode exhibiting a first Seebeck coefficient, a second electrode exhibiting a second Seebeck coefficient greater than the first Seebeck coefficient, and particles between the first and second electrodes exhibiting a third Seebeck coefficient between the first and second Seebeck coefficients. An alternating current power supply is electrically connected to the first and second electrodes. Heat is generated due to the Peltier effect at a junction between the first electrode and the particles and at a junction between the second electrode and the particles. Heat is removed due to the Peltier effect at the junction between the first electrode and the particles and at the junction between the second electrode and the particles. The particles are densified due to heating and cooling phase transitions between a higher-temperature solid phase and a lower-temperature solid phase while compressing the particles.
