Abstract

Bu çalışmada CAS (CaO-Al₂O₃-SiO₂)
seramikleri zeolit, mermer tozu ve alümina tozları kullanılarak; 400 dev/dk ve
600 dev/dk hızlarında mekanik aktivasyon ile üretilmiştir. Aktive edilen tozlar
pres yardımı ile şekillendirildikten sonra 1000^oC-1200^oC
sıcaklık aralığında 1-5 saat süre ile sinterlenmiştir. Aktivasyon öncesi ve
sonrası tozların ve sinterlenmiş ürünlerin faz analizi XRD yöntemi ile
belirlenmiş; mikroyapı analizleri ise SEM ile görüntülenmiştir. Aktivasyon
sonrası tozlarda amorflaşma tespit edilirken, aktivasyon hızının artması ile
tane boyutu azalması ile beraber aglomerasyonlaşma da gözlenmiştir. Sinterleme
sonucu gözenekli yapı oluşmuş; sıcaklık 1200^oC’ye çıktığında gözenek
çapı belirgin şekilde artmıştır.

Effect of mechanical activation on CAS ceramics from produced using zeolite and marble powder

Abstract

In this
study, CAS (CaO-Al₂O₃-SiO₂) based ceramics were
produced by mechanically activation at speeds of 400 and 600 rpm using zeolite,
marble powders and alumina. The activated powders were sintered at 1000-1200^oC
temperature for 1-5 hours after shaped by hydraulic press. Phase analysis of
activated and non-activated powders and sintered products were determined by
XRD method. Scaning electron microscopy (SEM) was used to analyze the
microstructure of samples. After activation amorphization was detected in the
powders, while agglomeration was observed with the increase of the activation
rate and the decrease of the grain size. As a result of sintering, a porous
structure was formed; when the temperature went up to 1200 ^oC, the pore
sizes increased noticeably.
