Abstract
The invention relates to a crucible for melting and crystallizing a metal, a semiconductor material, or a metal alloy, wherein a crucible wall of a crucible base body is made at least partially of a crucible material comprising silicon nitride and silicon dioxide at a weight ratio of between about 1:10 and about 1:1 (Si3N4 : SiO2). The invention further relates to a component for a crucible base body of a crucible for melting and crystallizing a metal, a semiconductor material, or a metal alloy, wherein a component segment is made at least partially of a crucible material comprising silicon nitride and silicon dioxide at a weight ratio of between about 1:10 and about 1:1 (Si3N4 : SiO2), and to a method for producing a component for a crucible base of a crucible for melting and crystallizing a metal, a semiconductor material, or a metal alloy, wherein a component segment is formed at least partially of a crucible material comprising silicon nitride and silicon dioxide at a weight ratio of between about 1:10 and about 1:1 (Si3N4 : SiO2).

Abstract
The invention relates to a method for joining workpieces by bonding, wherein a workpiece region formed on a workpiece and made of a TiAl alloy and a workpiece region formed on another workpiece and made of a TiAl alloy, or a high-temperature material different from the TiAl alloy, are joined in a joining region using a joining additive, wherein the joining additive contains at least one of the elements of gallium and indium. The invention further relates to a method for applying material onto a workpiece, wherein an application material is applied onto a workpiece region made of a TiAl alloy in that a bonded connection is established between the application material and the workpiece region, wherein the application material contains at least one of the elements of gallium and indium and a filler.
