摘要:
A glass ceramic composition includes a SrZrO3 ceramic, a Li2O—MgO—ZnO—B2O3—SiO2-based glass, Mg2SiO4 in an amount of about 5 to 40 weight percent, and a SrTiO3 ceramic in an amount in the range of about 0 to about 6 weight percent of the total. The Li2O—MgO—ZnO—B2O3—SiO2-based glass accounts for about 1 to about 12 weight percent of the total.

It includes a CaZrO3-based ceramic and a Li2O—MgO—ZnO—B2O3—SiO2-based glass. The Li2O—MgO—ZnO—B2O3—SiO2-based glass is 1 to 12 percent by weight of the total composition, the content of Li2O is 3.5 to 15 percent by weight, the content of MgO is 20 to 50 percent by weight, the content of BaO is 0 to 25 percent by weight, the content of CaO is 0 to 10 percent by weight, the content of SrO is 0 to 25 percent by weight, the content of B2O3 is 16 to 29 percent by weight, the content of SiO2 is 11 to 35 percent by weight, the content of ZnO is 5 to 20 percent by weight, and the content of Al2O3 is 0 to 15 percent by weight. This glass ceramic composition is advantageously used for green glass ceramic layers to form a green laminate structure useful as a main component body of an LC filter or the like.

摘要:
Disclosed are a belt member having high wear resistance and thereby capable of maintaining its initial surface properties for a long period of time and a fixing device provided with, the belt member, and an image forming apparatus. The belt member has a belt shape, and its surface is formed of a cured resin including a structural unit derived from urethane (meth)acrylate (A) having at least three (meth)acryloyloxy groups per molecule, a structural unit derived from a polyfunctional monomer (B) having no urethane bond and having at least three (meth)acryloyloxy groups per molecule, and a structural unit derived from a fluorine-modified acrylate (C). The cured resin contains 18 to 63% by mass of the structural unit derived from the urethane(meth)acrylate (A), 18 to 63% by mass of the structural unit derived from the polyfunctional monomer (B), and 10 to 40% by mass of the structural unit derived from the fluorine-modified acrylate(C).

摘要:
A multilayer ceramic substrate having high transverse strength, minimized warpage, and no delamination, has a laminated structure including an inner layer portion and surface layer portions, in which the thermal expansion coefficient of the surface layer portions is lower than the thermal expansion coefficient of the inner layer portion, the difference in thermal expansion coefficient between the surface layer portions and the inner layer portion is about 1.0 ppmK−1 or more, and the weight content of a component common to both a material constituting the surface layer portions and a material constituting the inner layer portion is about 75% by weight or more.
摘要:
An insulating ceramic composition includes a mixture of a ceramic powder containing MgAl2O4 and a glass powder containing 30-60% by mole of silicon oxide on the basis of SiO2 and 20-55% by mole of magnesium oxide on the basis of MgO, and the ceramic powder further includes Mg2SiO4 and TiO2. The insulating ceramic composition can be fired at 1000° C. and co-sintered with Ag and Cu. An insulating ceramic obtained by sintering the insulating ceramic composition has a high Q-factor and is therefore suitable for ceramic multilayer substrates used at high frequencies.
