FIELD: physics.
SUBSTANCE: method of making nuclear fuel tablets involves preparing starting powder, pressing the power in a conical matrix and sintering the obtained tablet. The powder is pressed by one-sided compression in the direction of the opening angle of the matrix. The matrix used has taper angle selected based on the condition of providing equal diameters on the faces of the tablet after sintering, taking into account diameter shrinkage of the faces of the tablet during sintering due to loss of pressure on the height of the raw tablet when pressing under the action of frictional forces.
EFFECT: high utilisation factor of expensive material, high quality of fuel tablets and longer service life of the pressing tool.
