摘要： PROBLEM TO BE SOLVED: To industrially mass-produce an inorg. powdery pigment excellent in heat resistance, assuming various clear hues and not causing environmental pollution. SOLUTION: This inorg. powdery pigment is a powdery multiple metal oxide contg. Ti and two kinds of divalent metals M1 and M2 selected from among Mg, Fe, Ni and Co. In the multiple metal oxide, the atomic ratio of M1+M2 to Ti is 1 and the atomic ratio of M1:M2 is within a range of 95:5 to 5:95. This pigment is obtained. by heat-baking a mixture of M1 and M2 compound powder with TiO2 powder in the temp. range of 1,000-1,350 deg.C and pulverizing the resultant product.

摘要： PROBLEM TO BE SOLVED: To provide the production process of well-oriented platelike spinel-type ferrite powdery particles which are appropriately used as a radio wave absorptive material or electromagnetic-shielding material. SOLUTION: This production process for producing the objective platelike spinel-type ferrite powdery particles, consists of a first stage and a second stage. The first stage comprises: adding a water-soluble salt of Ni or its aqueous solution to an aqueous liquid suspension of platelike hematite powdery particles; thereafter, adjusting the pH of the resulting suspension to 9.0-14.0; aging this suspension at 0-30 deg.C to coat the surface of each of platelike hematite particles with hydroxide or oxide of Ni; and thereafter, calcining the coated hematite particles at 500-700 deg.C by heating them to obtain powdery particles of an Ni-containing platelike calcined material. The second stage comprises: adding a water-soluble salt of Ni or its aqueous solution to an aqueous liquid suspension of the Ni-containing platelike calcined material powdery particles obtained in the stage 1; thereafter, adjusting the pH of the resulting suspension to 9.0-14.0; aging this suspension at 0-30 deg.C to coat the surface of each of the Ni-containing platelike calcined material powdery particles with hydroxide or oxide of Ni; and thereafter, firing the coated powdery particles at 800-1,200 deg.C by heating them to obtain platelike spinel-type ferrite powdery particles.

摘要： PROBLEM TO BE SOLVED: To obtain the subject composition capable of removing hydrogen chloride in an incinerator and controlling the evolution of a hydrogen chloride gas in incineration together with a waste containing plastic waste, etc., by compounding a synthetic resin with a specific compound. SOLUTION: This composition comprises (A) 99-50 pts.wt. of a synthetic resin and (B) 1-50 pts.wt. of hydroxysodalites [Na8Al6Si6O24(OH)2]. For example, a thermoplastic resin such as a polyethylene, a propylene, etc., may be cited as the component A. The component B can be obtained, for example, by mixing kaolin with sodium carbonate in equal amounts, calcining the mixture at 700 deg.C for 1 hour, kneading the calcined mixture with an aqueous solution of sodium hydroxide in the molar ratio of 1/3 to prepare a paste and subjecting the paste to hydrothermal treatment at 150 deg.C for 24 hours. A waste bag comprising the composition as a material is incinerated to remove hydrogen chloride evolved in a incinerator and to consequently control the generation of dioxin.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing a colored slaked lime for a lime plaster containing a coloring substance uniformly dispersed therein and hardly causing an irregular color. SOLUTION: An inorganic material powder as a coloring substance is added to a limestone powder, baked and then slaked to produce a colored slaked lime for a lime plaster. The limestone is preferably a powder having 0.01-0.5mm average particle diameter. An inorganic material such as a pigment or further a sludge prepared by washing the limestone with water is used as the coloring substance. The amount of the coloring substance added thereto is preferably within the range of 1-20wt.% in the limestone. The baking temperature is preferably within the range of 900-1,300 deg.C. Since the sludge when washing the limestone with water contains calcium carbonate at a high concentration, the sludge can directly be used for baking.
