Abstract:
1. A thermocautery block, comprising a rectangular bock formed by mixed different materials, including alumina 15-50 wt %, zirconium silicate 5 wt %, feldspar 26 wt %, pottery stone 8 wt %, siliceous limestone 4 wt %, kaolin 20 wt %, gairome clay (Japan) 7 wt %, and black soil 5 wt %, with water and evenly stirring the mixture; compressing and dehydrating the mixture into lump; stirring the compressed and dehydrated lump again and then vacuum extruding the lump into bars, which are then compressed into polygonal blocks; putting the polygonal blocks in the an airy environment for air drying; kilning the air-dried polygonal blocks through slow combustion at a temperature up to 1200-1300° C.; and allowing the kilned blocks to cool at room temperature naturally to provide a finished block that has a high density and a hardness of more than 6.0, and is able to store thermal energy after being heated for a short time and progressively release the stored thermal energy via superficial areas of the finished block other than corners thereof to create a progressive temperature rise.
