An at least partially crystallized glass includes at least one crystal phase and pores which are distributed in the at least partially crystallized glass in a structured manner.

Bond produced with an at least partially crystallized glass, such as a metal-to-glass bond, in particular a metal-to-glass bond in a feed-through element or connecting element, and method for producing such a bond, in particular in a feed-through element or connecting element

The present disclosure relates to pane-like articles, such as glass or glass ceramic substrates, suited for microwave-shielding applications, such as microwave oven doors or covers for electronic components. The present disclosure further relates to a household appliance comprising a pane-like article.

The present invention relates to glasses having a composition made up of base glasses. The glasses have a good chemical toughenability in combination with an advantageous coefficient of thermal expansion. Owing to their composition and the production process, the homogeneity of the properties of the glasses at their surface is high compared to the bulk glass. Furthermore, the fragility of the glasses is low, so that they can be processed to produce very thin glass articles.

Glasses having improved ion exchangeability and thermal expansion

The disclosure relates to a glass and a melt solder for the passivation of semiconductor components, the use of the glass or the melt solder for the passivation of semiconductor components, a passivated semiconductor component and a method for passivating semiconductor components.

The disclosure relates to a bond produced with an at least partially crystallized glass, such as a metal-to-glass bond, in particular a metal-to-glass bond in a feed-through element or connecting element, and to a method for producing such a bond, in particular in a feed-through element or connecting element. The at least partially crystallized glass includes at least one crystal phase and pores which are distributed in the at least partially crystallized glass in a structured manner.

A composite material is provided that includes at least one first material and particles. The particles have a negative coefficient of thermal expansion and the particles have a sphericity &#x3a8; of at least 0.7. The composite material includes at least 30 vol % of the particles at a particle size of d&#x2264;1.0 &#x3bc;m or at least 40 vol % of the composite material at a particle size d&#x3e;1.0 &#x3bc;m.

Composite material and adhesive bonding material having the composite material

The present invention relates to an improved cordierite glass-ceramic. In order to improve the materials properties, it is proposed that the glass-ceramic comprising SiO, AlO, MgO and LiO contains cordierite as main crystal phase and that a secondary crystal phase of the glass-ceramic comprises high-quartz solid solution and/or keatite solid solution. The invention further relates to a process for producing such a glass-ceramic and the use of such a glass-ceramic.

Cordierite glass-ceramic

A glass-ceramic is disclosed, this glass-ceramic includes at least the following constituents (in mol % on oxide basis): SiO1-30, AlO0-20, BO0-25, TiO10-70, REO0-35, BaO 5-35, SiO+AlO+BO&#x3c;25, where RE is lanthanum, another lanthanoid, or yttrium, and where Ti may be replaced in part, preferably up to 10%, by Zr, Hf, Y, Nb, V, Ta. A principal phase in the glass-ceramic is BaTiO.
