  • Specific applications of the fibers of the present invention include heat treatment equipment, joint materials in furnaces such as industrial kilns and incinerators, joint materials for filling gaps such as refractory tiles, heat insulating bricks, iron skins, mortar refractories, sealing materials, Packing material, cushioning material, heat insulating material, fireproofing material, fireproofing material, heat insulating material, protective material, coating material, filter material, filter material, insulating material, jointing material, filler, repair material, heat resistant material, noncombustible material, soundproofing material , Sound-absorbing materials, friction materials (for example, brake pad additives), glass plate / steel sheet transport rolls, automobile catalyst carrier holding materials, various fiber reinforced composite materials (for example, fiber reinforced cement, fiber reinforced plastic and other reinforcing fibers, heat resistance Materials, reinforcing fibers of refractory materials, reinforcing fibers such as adhesives and coating materials), and the like.
  • various fiber reinforced composite materials for example, fiber reinforced cement, fiber reinforced plastic and other rein
  • Examples 1-8 The fiber composition shown in Table 1 was examined as follows. First, the raw materials were mixed so as to have the composition shown in Table 1, and pressed to obtain a molded body. The molded product was melted by heating and rapidly cooled to obtain a sample. Using this sample, the following method was used for evaluation. The results are shown in Table 1.
  • Biosolubility 1 g of a sample was placed in an Erlenmeyer flask (volume: 300 mL) containing 150 mL of pH 4.5 physiological saline. This flask was placed in an incubator at 37 ° C., and horizontal vibration at 120 revolutions per minute was continued for 2.5 hours. Thereafter, the amount (mg) of each element contained in the filtrate obtained by filtration was measured with an ICP emission spectrometer, and the total was taken as the elution amount (mg / sample 1 g).
  • Alumina reactivity A sample was molded to obtain a cylindrical sample having a diameter of about 7 mm and a thickness of about 5 mm. This cylindrical sample was placed on an alumina plate and heated at 1400 ° C. for 8 hours to observe the presence or absence of adhesion or melting. It was 4 when the cylindrical sample was melted, 3 when it was adhered, 2 when it was not adhered but remained, and 1 when it was not adhered and remained.
  • the inorganic fiber of the present invention can be used for various purposes as a heat insulating material or as a substitute for asbestos.
