<p>A method is disclosed for the making of compressed refractory fiber shapes, having a textured surface and an aggregate body. Small discrete fragments of refractory fiber in accumulated form are suspended in a colloidal dispersion. The fragments and the dispersion are mildly mixed so as not to thoroughly disperse the fiber fragments, but rather to form globules of the fiber in the resulting blend. The resulting material is shaped, e.g., molded under pressure, and usually dried while under pressure. Resulting shaped objects, in addition to a textured surface and an aggregate body, can have excellent thermal insulation property, and desirable flexibility as well as tensile strength.</p> |
