摘要:
The present invention is an electroconductive particle for forming an electrode including a precious metal particle including Pt or a Pt alloy and having an average particle diameter of 50 to 150 nm, a first ceramic particle including Al 2 O 3 or ZrO 2 dispersed in the precious metal particle and having an average particle diameter of 5 to 50 nm, and a second ceramic particle including Al 2 O 3 or ZrO 2 bonded to an outer periphery of the precious metal particle and having an average particle diameter of 5 to 50 nm. The sum of the volume of the first ceramic particle and the volume of the second ceramic particle is preferably 2 to 40 vol% based on the whole electroconductive particle. A metal paste containing the electroconductive particle according to the invention is one from which an electrode film of low resistance and excellent durability can be manufactured and further excellent in adherence and conformability to a substrate.

A black ceramic composite coating is presented. The ceramic composite coating comprises a ceramic matrix having embedded therein carbide nanoparticles (in particular metal carbide nanoparticles) and/or metal-carbon composite nanoparticles (with separate metal and carbon phases) embedded therein. The carbide nanoparticles are metastable and the metal-carbon composite nanoparticles are decay products of the metastable carbide nanoparticles. A further aspect of the invention relates to producing such a ceramic composite coating.

摘要:
A concrete reinforcing member for admixture into a concrete composite. The concrete reinforcing member has a body extending in a longitudinal direction along an axis, the body having a lateral width. At least two anchor segments are axially spaced on the body, each anchor segment having at least one lateral extension projecting in a lateral direction along an associated plane that extends radially relative to the axis of the body. The associated plane of the lateral extension of one of the anchor segments is offset radially about the axis at an angle of greater than 0° and less than 90° relative to the associated plane of the lateral extension of the other anchor segment.

摘要:
A ductile ceramic composite comprising a ceramic phase and a continuous, ordered, ductile, metallic array, said ductile array being embedded in and surrounded by said ceramic phase. The composite can be flexed without fracturing or spalling and has a wide range of applications depending upon the ceramic and ductile phases selected.
摘要:
A composite material is provided which includes a discrete phase including grains made of a first substance; and a continuous phase including a thin coating film made of a second substance and formed on the surface of each of the grains. The thin coating film has a mean thickness smaller than the mean particle size of the grains. The grains are separated substantially from each other by the thin coating film. The porosity of the composite material is 5% or less.
