EFFECT OF PARTICLE SIZE OF ALUMINUM ON THE DEVELOPMENT OF CLINOPTILOLITE BASED POROUS CERAMIC FILTERS
Abstract
This paper reports the effect
of particle size of Al-metal powder addition on the development of
clinoptilolite based porous ceramic filters. The clinoptilolite particles was
mixed with 10 wt.% of Al-powder and the three different clinoptilolite-metal powder mixture samples were prepared
namely: (i) coarse sample (used large size of Al-powder by mixing in dry ball
mill for 5 min.), (ii) moderate sample (using fine size of Al-powder) and (iii)
fine sample (planetary milling of the moderate sample in an aqueous medium for
1 hour). The mixtures were shaped by uniaxial pressing at 50 MPa and later
sintered at the temperatures of 1200°C for 1 hour under air atmosphere. The microstructure and phase evolution were
investigated by SEM and XRD, respectively. The coarse sample indicated corundum
crystallization with silicon (Si) and with poor cristobalite crystallization.
The cristobalite crystallization is prodominantly for the fine and moderate
samples. Except the planetery milled sample (fine) the porosities of the
samples were good enough (~28%) but the pore sizes were different; the
coarse sample showed large pores up to 150 mm in size, the moderate sample produced relatively fine and narrow pore
size distribution (4-65 mm). The
results indicated that the moderate sample leads to production of ceramic
filter with high selectivity during filtration.

Abstract
Bu makalede,
klinoptilolit tabanlı seramik filtrelerin üretiminde tane boyutu etkileri
araştırılmıştır. Burada klinoptilolit tozları ağırlıkça % 10 Al tozu ile
karıştırılmış ve üç farklı klinoptilolit-metal toz karışımı örneği
hazırlanmıştır: (i) iri taneli numune (iri boyutlu Al tozları kuru olarak
bilyalı değirmende 5 dakika boyunca karıştırılmıştır), (ii) orta taneli numune (ince
boyutlu Al-tozu kullanılmıştır), ve (iii) ince taneli numune (orta taneli
numune planetary değirmende 1 saat öğütülmesi ile hazırlanmıştır). Karışımlar,
50 MPa basınç değerinde tek eksenli presle şekillendirilmiş ve daha sonra
oksijen atmosferde 1200°C'de 1 saat süre ile sinterlenmiştir. Mikroyapı ve faz
gelişimi SEM ve XRD analizleri ile araştırılmıştır. İri taneli numunede,
korundum, silisyum (Si) ve düşük oranda kristobalit fazında kristalleşme elde
edilmiştir. İnce ve orta taneli numunelerde ağırlıklı kristallenme
kristobalittir. Planetary değirmende öğütülmüş numunede gözeneklilik düşüş
gösterirken iri ve orta boyutlu tanelerin kullanıldığı numunelerde gözeneklilik
~%28 oranındadır, ancak gözenek boyut dağılımları farklılık göstermiş ve iri
boyutlu tanelerin kullanıldığı numunede 150 mm'ye kadar büyük gözenekler gözlenmiştir.
Orta boyutlu tanelerin kullanıldığı numunelerde nispeten küçük ve dar bir
aralıkta gözenek dağılımı elde edilmiştir (4-65 mm).
Sonuçlar, orta boyutlu tanelerin kullanıldığı numunenin filtrasyon
sırasında yüksek seçiciliğe sahip seramik filtrenin üretimine imkan sağladığını
göstermektedir.
