Study of the Crystallization in a Glass-Ceramic Seal
Abstract
<jats:p>Sealing is a major issue in Solid Oxide Cells (SOC) stacks used for hydrogen production. The specifications that seals must meet are particularly demanding. Glass-ceramics such as materials from the MgO-Al<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>-BaO-SiO<jats:sub>2</jats:sub>-B<jats:sub>2</jats:sub>O<jats:sub>3 </jats:sub>system are used. A preliminary treatment allows the initially amorphous material to set up while partially crystallizing. This paper presents the crystallization study of such a material. The main Ba<jats:sub>5</jats:sub>Si<jats:sub>8</jats:sub>O<jats:sub>21</jats:sub> and BaMg<jats:sub>2</jats:sub>Si<jats:sub>2</jats:sub>O<jats:sub>7</jats:sub> crystalline phases are identified and the evolution of crystals morphology with the temperature is followed. The Ba<jats:sub>x</jats:sub>Si<jats:sub>y</jats:sub>O<jats:sub>x+2y </jats:sub>surface fraction is determined by image analysis as a function of time and temperature. These data allow accessing the equilibrium crystal fraction. It is then possible to optimize the crystallization treatment and to anticipate the microstructural evolution of the glass-ceramic seal operating in the stack.</jats:p>
