An inexpensive rotary grinding tool with reduced noise level of the grinding is provided. The rotary grinding tool comprises a metal disk having a grinding surface on at least a part of its surface and a holder for supporting the metal disk. The grinding surface has hard grains having a Mohs hardness in excess of 9 brazed thereon at a surface density of at least 20 grains/cm. The holder has at its center a securing means for securing the holder on rotary shaft of a rotary drive unit. The holder and the metal disk are joined together to constitute the rotary grinding tool.

Rotary grinding tool and its production method

The present invention provides metal fine particles which have selective wavelength absorption characteristics in a wavelength region from visible light to near infrared light, and have sharp absorption characteristics, and influences little the surrounding wavelength, and therefore, they yield tones having high chroma. The present invention provides metal fine particles wherein an aspect ratio is in a range from 1.1 to 8.0, a maximum absorption wavelength in plasmon absorption is in a range from 400 nm to 1,200 nm, and an absorption coefficient at a peak position of the maximum absorption wavelength is in a range from 6,000 to 20,000 L/mol&#xb7;cm (measurement concentration: 1.6&#xd7;10mol/L, and solvent: water).

Metal fine particles, composition containing the same, and production method for producing metal fine particles

A method for manufacturing metal nanorods includes: a step of adding a reducing agent to a metallic salt solution; a step of radiating light into the metallic salt solution containing the reducing agent; and a step of leaving the light-radiated metallic salt solution containing the reducing agent stationary in a dark place so as to grow metal nanorods. Metal nanorods can be also grown by forming a mixed solution by fractionating the above light-radiated metallic salt solution and mixing the fractionated metallic salt solution into a non-radiated metallic salt solution containing the reducing agent, or mixing a non-radiated metallic salt solution and the reducing agent into the above light-radiated metallic salt solution; and leaving the mixed solution stationary in a dark place so as to grow metal nanorods.

It is an object of the present invention to provide an anticorrosive coating composition which uses a pollution-free (heavy metal-free) rust preventive pigment and exhibits anticorrosive performances equal or superior to those of lead compounds or chromic acid compounds even if the pigment is blended in various binder resins and also to provide an anticorrosive coating composition having excellent storage stability. The present invention relates to an anticorrosive coating composition comprising a binder resin and a pollution-free (heavy metal-free) rust preventive pigment containing a condensed calcium phosphate produced by baking a single substance or mixture of a calcium component and a phosphorous component in the following atomic ratio (Ca/P=m): 0.50&#x3c;m&#x3c;1.00, at 180 to 350&#xb0; C.

Anticorrosive coating compositions

An organic composite coated steel sheet having excellent chromate dissolution resistance, wet adhesion, and corrosion resistance before and after working. The steel sheet comprises a chromate-silica film on at least one face of a zinc or zinc base alloy plated steel sheet, the silica-added chromate film having about 5 to 500 mg/m.sup.2 in terms of metal Cr content and being formed from a chromate solution containing about 25 to 70 wt % of Cr.sup.+6 based upon total Cr content. A resin coating film is adhered to the chromate-silica film and is formed from an aqueous paint. The aqueous paint includes an aqueous anionic resin and/or an aqueous nonionic resin, a reducing agent, and a water-dispersed silica. The resin coating film is deposited in a dry weight amount of about 0.1 to 3 g/m.sup.2.
