Sillimanite Refractory Bricks: Check the Grade and Shape Together
Material name, dimensions, and service conditions all matter when specifying a sillimanite brick.
Sillimanite identifies a material family, not a complete refractory brick specification. A buyer still needs the grade's chemistry, physical properties, intended temperature range, and the exact shape required by the lining. A standard brick and a special tile can serve different locations even when they share a material description.
Start from the exposure
Record the hot-face temperature, atmosphere, chemical contact, cycling, and mechanical load. Ask for the proposed brick's data sheet and check its test conditions. A material family name alone does not establish resistance to a specific process contaminant or thermal-shock duty.
Define the supplied shape
Show dimensions, orientation, tolerances, and joint layout on the drawing. For replacement work, compare the new shape with an unworn reference and the latest approved drawing rather than measuring only a damaged piece. Confirm quantity by each size and shape.
