摘要： Disclosed is calcium carbonate treated with a curing active ingredient, which, when compounded in a rubber, enables to provide good workability (handling) to the rubber and maximize advantageous properties of the rubber attributable to calcium carbonate (e.g., slip resistance) without deteriorating the reinforcing property of the rubber. The calcium carbonated treated with a curing active ingredient is produced by mixing a modified calcium carbonate having its surface treated with a fatty acid or a resin acid and silicic acid and having an average primary particle diameter of 0.01 to 0.5 μm with a curing active ingredient which takes a liquid form at ambient temperature so that the content of the curing active ingredient in the finished product becomes 9.1 to 35 wt %.

摘要： A light reflecting body includes a base containing a resin material and a calcium carbonate and includes a metal layer on the surface of the base. The resin material is selected from a polyester resin composition, a polyarylate resin composition, and a mixed resin composition thereof. The calcium carbonate has a BET specific surface area of 1 to 15 m2/g, a pore distribution curve determined by mercury porosimetry that the top of a peak representing interparticle void size is in a pore size range of 0.1 to 1.0 μm, a particle size distribution determined by using an electron microscope that the proportion of particles having a particle size of 0.1 μm or less is 10% or less of the calcium carbonate, and the residue on a sieve having a mesh size of 45 μm after wet sieving of the calcium carbonate is 0.1% or less.

摘要： Provided is a surface-treated calcium carbonate that can make a vinyl chloride-based resin composition less colorable in a weathering test and excellent in impact strength. The surface-treated calcium carbonate is a calcium carbonate subjected to treatment with a surface treatment agent in which a proportion of saturated fatty acid contained in a fatty acid is 85% by mass or more, and has a content of elemental iron of 0.01% by mass or less, a content of elemental zinc of 0.1 to 2% by mass introduced by the treatment with the surface treatment agent, and a BET specific surface area of 5 to 30 m2/g.

摘要： An object is to provide a particle that has properties to seal dentinal tubules, and that exhibits excellent adhesion in dentinal tubules. The object is achieved by a fine hydroxyapatite particle that has a ratio of the diffraction peak intensity around 2θ=32° to the diffraction peak intensity around 2θ=26° of 0.8 to 1.6 in an X-ray diffraction pattern as measured by using CuKα radiation, and that is an aggregate of particles.
