摘要： PROBLEM TO BE SOLVED: To provide a rock wool molded form suitable for a culture medium for cultivating plants, and capable of being produced without complicating its production process.
SOLUTION: This rock wool molded form comprises a mixture of a rock wool mat (A) with aggregates S; wherein the aggregates S mostly exist at the lower side in the thickness direction of the mat and to the upper side they exist fewer they get so as to increase the gas phase amount of the lower layer of the mat. By this structure, the gas phase amount is highly maintained by increasing the density at the lower layer of the rock wool mat, and as a result, defects such as root rot of plants due to over-humidity can be eliminated.

摘要： PROBLEM TO BE SOLVED: To absorb thermal shocks and physical shocks which are imposed on the inner surface of a burner structure and suppress generation of cracks, by holding a liner member with a restoring force of a compressed inorganic fiber forming blanket, the liner member functioning as a nozzle for introducing flames, high-temperature gases and the like to an incinerator. SOLUTION: In setting a burner structure for introducing flames, high- temperature gases and the like into an incinerator, inorganic fiber forming boards 10a are, first of all, bonded with a heat-resisting bonding agent 10b so as to form a surrounding wall portion 10. Then, a hollow 11 is formed by scooping out the inside of the surrounding wall portion 10. Subsequently, the outer periphery of a liner member 13 is wrapped with an inorganic fiber blanket 12, and the inorganic fiber blanket 12 is tightly bound by means of a plurality of tape-like tightly-binding members 14 so as to maintain a compressed condition and to be fitted into the hollow 11. After being fitted, the tightly-binding members 14 are burned out by high-temperature fire, so that the inorganic fiber blanket 12 is released from the compressed condition, and thus the liner member 13 is held in the hollow 11 by a restoring force (rebound force) of the inorganic fiber blanket 12.

The acidic colloidal silica (B) has a low Na content so as not to deteriorate the heat resistance of stock fibers. The silica fibers (C) are high purity silica fibers having >=95wt.% SiO2 content, 0.3-3μm average fiber diameter and 1-5mm average fiber length. The boron compd. (D) is, e.g. boron oxide. The amt. of the component B is 10-30wt.% of the total amt. of the components A, C. The amt. of the component A is 75-95wt.% of the total amt. of the components A, C. The amt. of the component D is 3-5wt.% (expressed in terms of B2 O3 ) of the total amt. of the components A, C.

摘要： PROBLEM TO BE SOLVED: To improve the isotropy and uniformity of physical properties, heat resistance and strength by heating a formed compact of an aluminum borate whisker-forming raw material mixture and pressing a metal into void parts of the resultant porous ceramics having the produced aluminum borate whiskers therein. SOLUTION: An aluminum compound is mixed with a boron compound so as to provide 9:(2-6) molar ratio of Al2 O3 :B2 O3 and 0.1-10wt.% (expressed in terms of NiO) nickel compound is then added to the resultant mixture to afford an aluminum borate whisker-forming raw material mixture, which is then compression formed to provide a formed compact. The resultant compact is subsequently heated at 1100-1400 deg.C in air to afford porous ceramics having fine communicating voids of mutually bonded aluminum borate whiskers and 50-95% void ratio. The prepared ceramics are preheated and a metal for a matrix in a molten state is pressed into the void parts. The resultant ceramics are then cooled to solidify the metal.
