Abstract

Within the scope of present work, porous and lightweight anorthite ceramics by utilizing admixtures of eggshell waste, fireclay, and expanded polystyrene (EPS) addition has been produced. First, samples of mixtures prepared with different proportions of eggshell waste were fired at different temperatures in order to determine the appropriate anorthite composition. Later, in order to produce high porosity anorthite ceramics, different amounts of EPS are added to the most suitable composition determined and porous samples were produced by firing at the certain temperature. The high degree of porous anorthite ceramics from the admixtures in the range of 0 to 30 vol.% EPS addition were satisfactorily fabricated. The physical characteristics, compressive strength and thermal conductivity were examined. Thermal conductivity of the anorthite ceramics showed a decline from 0.39 W/m·K (1.00 g/cm3) to 0.11 W/m·K (0.78 g/cm3) in proportion to the decrease in density. It has been found from the results in which these porous materials produced by the reuse of eggshell waste are suitable for use in various applications requiring elevated temperatures.

Özet

Mevcut çalışma kapsamında yumurta kabuğu atığı, ateş tuğlası ve genleştirilmiş polistiren (EPS) karışımları kullanılarak gözenekli ve hafif anortit seramikler üretilmiştir. İlk olarak, farklı oranlarda yumurta kabuğu atığı ile hazırlanan karışım numuneleri, uygun anortit bileşimini belirlemek için farklı sıcaklıklarda pişirilmiştir. Yüksek oranda gözenekli anortit seramikler üretmek için belirlenen en uygun bileşime, farklı miktarlarda EPS ilavesi yapılmıştır ve belirli sıcaklıkta pişirilerek gözenekli numuneler üretilmiştir. Hacimce %0-%30 aralığında EPS ilavesi ile elde edilen karışımlardan başarılı bir şekilde yüksek gözenekli anortit seramikler üretilmiştir. Fiziksel özellikleri, basınç dayanımı ve ısıl iletkenlik değerleri incelenmiştir. Anortit seramiklerin termal iletkenliği yoğunluktaki azalmayla orantılı olarak 0,39 W/m·K (1,00 g/cm3)'den 0,11 W/m·K (0,78 g/cm3)'e bir azalma göstermiştir. Elde edilen sonuçlara göre, yumurta kabuğu atıklarının yeniden kullanılmasıyla üretilen gözenekli anortit seramiklerinin, yüksek sıcaklıklar gerektiren uygulamalarda kullanıma uygun olduğu bulunmuştur.
