摘要： PURPOSE:To provide the subject composition prevented in a pseudo- crystallization phenomenon and shortening a period required for kneading by adding a fine amount of slaked lime to a castable flame-resistant composition containing alumina cement and a sulfonic acid group-containing surfactant. CONSTITUTION:In a method for preparing a castable flame-resistant composition mixed with alumina cement and a sulfonic acid-containing surfactant, a fine amount of slaked lime is added. The slaked lime to be added is especially not restricted but may be added in an amount of approximately 2wt.%, based on other components in the castable flame-resistant composition.

摘要： PURPOSE:To obtain a raw material suitable for producing Ca compd. which is inexpensive and suitable as a material for producing calcium phosphate compds. having superior biocompatibility and useful as a material for implanting in living bodies such as artificial tooth, etc., by crushing natural shells. CONSTITUTION:The aimed raw material for calcium phosphate compd. is produced by crushing natural shells such as shells of short-necked clam, clam, corbicula, etc. The calcium phosphate compd. such as apatite, etc., is obtd. by allowing the obtd. powder body to react with phosphoric acid or phosphate compd. (e.g. pyrophosphoric acid) by mixing both, or by adding further, if necessary, alkali metal hydroxide (e.g., NaOH), alkaline earth metal hydroxide [e.g., Ba(OH)2], or compds. contg. carboxylic acid (e.g., tartaric acid, citric acid). By this process, natural shells to be wasted are utilized effectively and calcium phosphate compds. having high biocompatibility are produced.

摘要： PURPOSE: To improve workability with expressing adequate plasticity during an application, enlarging permissible range of an amount of added water, improving durability by suppressing used amount of a clay and bringing degrees of freedom in a material design by blending alginic acid and/or an alginate compound as a caking agent. CONSTITUTION: This stamp material contains 0.1-2.0wt.%, of alginic acid and/or an alginate compound. Thus, the stamp material can express adequate plasticity during an application even if a large amount of a clay is not blended. A range of a permissible amount of added water is widened. Thus, it can be possible to improve durability by decreasing a used amount of the clay and increase degrees of freedom of a material design. Further, the material can be used as a patching material by adjusting the amount of added water. As an alginate compound, e.g. sodium alginate, ammonium alginate, triethanolamine alginate, alginic acid propylene glycol ester, etc., can be used.

摘要： PURPOSE:To prevent the wear in a metal zone and to improve durability by adding oxidizing agents, such as V2O5, to the lining material for the tapping spout of a blast furnace contg. SiC as refractory aggregate. CONSTITUTION:At least one kind of the oxidizing agents, such as V2O5 and Mn2O3, are added to the lining material of the tapping spout of the blast furnace contg. the SiC as at least a part of the refractory aggregate. These oxidizing agents supply O in a low oxygen partial pressure area to suppress the formation of SiO and to form an SiO2 film, thereby suppressing gaseous phase cracking of the SiC. As a result, the lining material which wears less in the metal zone and has the excellent durability is obtd.
