الأبيض تنصهر الألومينا مقابل. Tabular Alumina for Ultra-High Temperature Refractories
Choosing between white fused alumina and tabular alumina for ultra-high-temperature refractories is a structural decision, وليس مجرد مقارنة التكلفة. This article examines the microstructural, الحرارية, and chemical properties that determine which material survives sustained service above 1600 °C — and where each grade delivers the better return on refractory investment.
