    Abstract: In a sintered body of low temperature cofired ceramic constituting ceramic layers of a multilayer ceramic substrate provided with external conductor films, which is obtained by sintering a non-glass low temperature cofired ceramic material, respective crystalline phases of quartz, alumina, and fresnoite are deposited. The ceramic layers are, because of being in the form of a sintered body of non-glass low temperature cofired ceramic, less likely to fluctuate in composition, and the multilayer ceramic substrate can be thus inexpensively and easily manufactured therefrom. In addition, the ceramic layers have the above-mentioned respective crystalline phases deposited therein, and thus have a high joint strength with the external conductor films, and moreover, the sintered body itself has a high fracture touhgness value.

  • Publication number: 20110193025
    Abstract: A method of forming nanometer sized fine particles of functional ceramic from a bulk functional ceramic, particularly fine particles of phosphorous ceramics from a bulk phosphor material is disclosed. The method relies on irradiation of a bulk phosphorous ceramic in a liquid with an ultrashort-pulsed-laser-fragmentation beam to thereby form nanometer sized particles of the phosphorous ceramic. The method is unique in that the generated particles retain the chemical and crystalline properties of the bulk phosphorous ceramic. The generated solutions are stable colloids from which the particles can be isolated or used as is.

  • Patent number: 7932203
    Abstract: A method for producing an oil-binding agent of granular open-porous structure with a silicate ceramic matrix by using recovered paper material and clay. The method is characterized in that, in each case based on the entire raw material, 35 to 60 wt.-% sewage sludge with a water content of between 70 and 85 wt.-%, 25 to 55 wt.-% recovered paper material with a water content of between 35 and 55 wt.-%, 10 to 25 wt.-% clay and optionally 1 to 3 wt.-% zeolite, 1 to 2 wt.-% quicklime and/or up to 3 wt. % fly ash are mixed to a homogeneous mixture. The raw material thus obtained is subsequently processed in order to form particles having an average diameter of 4 to 6 mm. The particles are then dried and subsequently burnt at 950 to 1050° C. The oil-binding agents produced according to said method have a bulk density of between 0.4 and 0.75 kg/1 and a oil-binding capability of 0.7 to 1.0 1 oil per oil-binder.
