Complexed refractory brick

Claim 1

A MECHANICALLY STABLE, UNITARY REFRACTORY BRICK MODULE HAVING A PREDETERMINED INTERNAL STRESS PATTERN AND A UNIFORM TESSELLATED TEXTURE THROUGHOUT ITS LENGTH, WIDTH AND DEPTH, SAID TESSELLATED TEXTURE BEING CHARACTERIZED BY INTEGRAL BUT DISTINCT ALTERNATING BODIES OF REFRACTORY MATERIAL HAVING DIFFERENT PHYSICAL AND CHEMICAL CHARACTERISTICS, SAID MODULE COMPRISING A PLURALITY OF LAYERS OF SAID BODIES IN CONTACTING RELATION, EACH LAYER COMPRISING A PLURALITY OF SAID ALTERNATING BODIES WITHTHE SIDES OF THOSE BODIES HAVING COMMON PHYSICAL AND CHEMICAL CHARACTERISTICS CONTACTING ONLY THE SIDES OF THOSE BODIES OF DIFFERENT PHYSICAL AND CHEMICAL CHARACTERISTICS, THE BODIES OF SAID COMMON PHYSICAL AND CHEMICAL CHARACTERISTICS IN A LAYER ALSO CONTACTING THOSE BODIES OF SAID DIFFERENT PHYSICAL AND CHEMICAL CHARACTRISTICS IN A CONTACTING LAYER, WHEREBY SAID BODIES OF SAID COMMON PHYSICAL AND CHEMICAL CHARACTERISTICS ALTERNATE WITH SAID BODIES OF SAID DIFFERENT PHYSICAL AND CHEMICAL CHARACTERISTICS THROUGHOUT THE LENGTH, WIDTH, AND DEPTH OF SAID MODULE.
