Strocera

Refractory crucibles.

Sinter-optimized α-Al₂O₃ for refractory crucibles in high-temperature melt and processing applications.

STROCERA / / / Alpha Alumina Powder / / / Industrial
[ 01 ]The challenge

Refractory crucibles run at high temperatures under chemically aggressive conditions. Microstructure, density, and purity drive thermal-shock and chemical-attack resistance.
