Manik-manik Keramik
0102030405
Manik Keramik Cina kanggo Aplikasi RCS
01
• Komposisi komponen seragam
• Distribusi ukuran gandum sing stabil lan permeabilitas udara
• Refractoriness dhuwur (1800°C)
• Resistance dhuwur kanggo nyandhang, remuk lan kejut termal
• expansion termal sethitik
• Fluiditas lan efisiensi ngisi sing apik amarga bentuke bunder
• Tingkat reklamasi paling dhuwur ing sistem gelung pasir
