Y-FZM 1400 is a dry powder mixture of Yttria and FZM (Fused Zirconia-Mullite) which, on adding around 40 wt% water and stirring forms a cementitious slurry that can be poured or cast into silicone molds to form parts. Y-FZM 1400 also can be used to cement/glue refractories together (such as Alumina). Cast parts can be removed from the mold after vibrating to remove air bubbles and then heating at 50-60 C to “set” the binder and allow removal from the silicone mold. Heating a cast part to 1375-1400 C results in nearly dense refractory transormed to highly stable Yttria phases (Yttrium Aluminate, YSZ, Yttrium Silicate). Y-FZM 1400 is ideal for making your own corrosion resistant refractory parts, reportedly stable with molten Aluminum, glasses, and steel. Usable to nearly 1400 C in all atmospheres.
