    Abstract: The present invention deals with the application and transmission of steady or time varying pressure under high/low, steady or time dependent temperatures and eliminates the potential danger for explosive events which is unavoidable in coventional techniques (with fluid media). The method consists of using an assembly of ceramic microspheres coated by a solid lubricant (for temperatures between -50°C and 1600°C and steady or monotonically increasing pressure) or a mixture of melted oxides with extremely high boiling points (for temperatures between 300° and 2700°C and steady or cyclically varied pressure). The invention is related to the fields or Mechanics of Materials, Fluid Mechanics, Technology of Ceramics, etc. The method is exemplified in the case of internal pressurization of tubular metallic specimens. The tests show uniform pressure transmission to the desired directions, very good efficiency (ratio of radial to axially imposed pressure), repeatability and elimination of the explosion danger and the associated costs.
