Liquid phase bonding of siliconized silicon carbide | …

Aluminium was used as a braze to join siliconized silicon carbide to itself. Brazes were carried out in the 700–1100 °C temperature range, in vacuum. A thick reaction layer forms in the ceramic adjacent to the braze film, due to reaction between the metal braze and the free silicon present in the ceramic matrix. The silicon concentration of the braze film reaches values well above the

For reaction-bonded silicon carbide ceramics, the silicon grain-boundary phase softened at the bonding temperature, allowing the butting faces to be "glued" together. Unlike the glassy grain-boundary phase for alumina ceramics, the silicon phase did not allow grain motion but always formed a discrete and continuous layer at the interface, even under optimum joining conditions.
