Also described is a component of a braking system made wholly or in part from the preform, and a method for making a preform in a fibre-reinforced ceramic composite material.

A heat-dissipating member includes aluminum oxide ceramics that includes crystal particles of aluminum oxide. The aluminum oxide ceramics includes 98 mass % or higher of aluminum in terms of Al.sub.2O.sub.3 with respect to 100 mass % of all constituents. The crystal particles have an average equivalent circle diameter of 1.6 μm or more and 2.4 μm or less. An equivalent circle diameter cumulative distribution curve of the crystal particles has a first diameter at 10 cumulative percent and a second diameter at 90 cumulative percent that is different from the first diameter by 2.1 μm or more and 4.2 μm or less.

A method of manufacturing a dielectric for a capacitor and a dielectric for a capacitor manufactured thereby are provided. A dielectric for a capacitor is prepared by calcining a precursor mixture containing lead, lanthanum, zirconium, and titanium to produce calcined powder, adding additives including sodium, potassium, and the like to the powder, and sintering the mixture at a low temperature, whereby the dielectric has a high density and a large dielectric constant.

A dielectric material which satisfies X9M characteristics and ensures operations over an extended period of time at 200° C. is provided.

The present invention relates to a suspension comprising 50-95% by weight of the total suspension (w/w) of at least one metallic material and/or ceramic material and/or polymeric material and/or solid carbon containing material; and at least 5% by weight of the total suspension of one or more fatty acids or derivatives thereof. In addition, the invention relates to uses of such suspension in 3D printing processes.
