摘要： The invention relates to a device for homogenising a glass melt. The aim of the invention is to completely avoid using a mechanical agitator or at least to minimise the size and drive power thereof. In order to achieve this, the inventive device is provided with the following elements: 1.1) a container constructed according to the Skull principle; 1.2) a high frequency coil for coupling electric energy into the container.

摘要： Commercially obtained combustion aids typically consist of cordierite, fused silica or Si/SiC, which cannot meet the high thermal and also mechanical requirements in the necessary context, or only in a highly limited manner. The invention relates to a glass-ceramic combustion aid in the form of a non-porous keatite glass ceramic without a vitreous surface layer. Said combustion aid has high thermal stability and resistance to thermal shocks, practically no mechanical interaction, especially no porosity and adhesive effects, with the product to be baked, and can also be obtained in large formats having small thicknesses, as a mechanically stable bearing plate.

摘要： The invention relates to transparent glass ceramics that can be darkened by adding vanadium oxide, said glass ceramics containing high-quartz mixed crystals as the major crystal phase. The invention further relates to a method for producing said glass ceramics and to various uses thereof. The inventive transparent glass ceramics that contain high-quartz mixed crystals as the major crystal phase and that can be darkened by adding vanadium oxide are characterized in that the glass ceramics, except for unavoidable traces, contain none of the chemical refining agents arsenic oxide and/or antimony oxide. The darkened glass ceramics are further characterized by a light transmission factor in the visible range of τ
