Abstract

A method and its corresponding rapid and repeated hot pressing apparatus for compacting refractory materials, whose method is characterized in that it consists of: A) maintain a mold at the compaction temperature or slightly higher, in a housing containing an atmosphere essentially free of oxygen, B) introduce a controlled amount of refractory material into the hot mold, C) apply a pressure of 50 to 1000 pounds/inch 2 (3.5 to 70.3 kg/cm2) to partially compact the refractory material, D) immediately bring the refractory material to the final compaction temperature, E) apply a pressure between 1000 and 5000 pounds/inch 2 (70.3 and 351 kg/cm2) to the refractory material until the material has been compacted to at least 95% of the theoretical density, F) loosen said pressure and immediately push the compacted refractory material out of the mold and G) rapidly cooling the compacted refractory material in an atmosphere essentially free of oxygen.
