A material for a gas turbine component, to be specific a titanium-aluminum-based alloy material, including at least titanium and aluminum. The material has a) in the range of room temperature, the &#x3b2;/B2-Ti phase, the &#x3b1;-TiAl phase and the &#x3b3;-TiAl phase with a proportion of the &#x3b2;/B2-Ti phase of at most 5% by volume, and b) in the range of the eutectoid temperature, the &#x3b2;/B2-Ti phase, the &#x3b1;-TiAl phase and the &#x3b3;-TiAl phase, with a proportion of the &#x3b2;/B2-Ti phase of at least 10% by volume.

The active brazing solder for brazing ceramic parts of alumina, particularly of high-purity alumina, contains a maximum of 12 wt. % Ti, a maximum of 8 wt. % Be, and less than 16.5 wt. % Fe, the remainder being Zr and any impurities that may be present. The active brazing solder has the following behaviour/features: Brazing temperature: lower than 1,000&deg; C.; the brazed joint is high-vacuum-tight over a long period of time; the coefficient of thermal expansion of the active brazing alloy is substantially identical to that of the alumina ceramic in the entire temperature range covered during the brazing process; the strength of the brazed joint between the two ceramic parts is so high that under tensile loading, fracture will result not at the joint, but in the adjacent ceramic; the pressure resistance of the active brazing solder is greater than 2 GPa; the active brazing solder is very good processable into powders having particle sizes on the order of 10 &mgr;m.
