JM23 insulation brick are processed through moulding under high pressure ans sintering at high temperature , and JM23 insulation bricks with feature of strong strength,steady bulk at high temperature and small creep rate, which are available for hot blast stove of large and middle size.
JM23 insulating brick uses high pure mullite as raw material, JM23 insulating bricks are made by adding alumina powder according to different type and then sintering in high temperature. JM23 insulation firebrick is the new energy saving material for insulation. JM23 insulation fire brick is produced accordance with German industrial standard that especially for export to foreign countries.
. Excellent compression strength,
