رمل مسبك السيراميك، المعروف أيضًا باسم NFS CERAMSITE-Nice Foundry Sand، هو نوع من جزيئات السيراميك ذات الشكل الكروي من صنع الإنسان والتي تتميز بالحراريات العالية والتمدد الحراري المنخفض الناتج عن الرش المنصهر من البوكسيت المنصهر. إنه يوفر طريقة بسيطة وفعالة في صناعة المسابك لتحسين جودة المسبوكات، وتقليل تكلفة الإنتاج وتجنب التلوث البيئي، لذا فهو أفضل بكثير من رمل السيليكا. وهو أيضًا بديل جيد لرمل الكروميت ورمل الزركون بسبب سعره المنخفض. في الوقت الحاضر، يتم الاعتراف بالرمل الخزفي في جميع أنحاء العالم باعتباره أحدث وأفضل الرمل المثالي للمسابك وله جدوى واسعة جدًا من التطبيقات للتطوير المستقبلي.
