Abstract

Pamukkale
(Denizli) bölgesinin kuzeydoğusunda yüzeyleyen Asartepe (LE2) ve Kızılburun
(LE3 ve LE4) formasyonlarından alınan üç adet kil örneğinin fiziko-kimyasal,
mineralojik ve termal özelliklerini incelemek için X-ışını floresans, termal
analiz, X-ışını kırınımı, Atterberg limitleri ve tane boyu analizi yöntemleri
kullanılmıştır. Farklı birimlerden alınan bu killerin kimyasal ve mineralojik
bileşimleri arasında çok büyük farklılıkların olmadıkları tespit edilmiştir.
Mineralojik olarak, kırmızı killerin (LE2) kuvars, az oranda hematit, kil
minerali olarak ise illit, az oranda kaolinit, klorit/simektit ve klorit
içerdiği belirlenmiştir. Marnlı killerin ise (LE3 ve LE4) kuvars, kalsit ve piroksen
içerdikleri kil minerali olarak da illit ve az klorit, kaolinit ve klorit/simektit
içerdikleri tespit edilmiştir. Kimyasal bileşim açısından, kırmızı killer
yüksek miktarda SiO₂ (%52.0), Fe₂O₃ (%7.7) ve
Al₂O₃ (%19.2) içermekte marnlı killer ise daha az oranda
SiO₂ (%40.1-44.5) ve Al₂O₃ (%12.7-14.0) ve
yüksek oranda CaO (13.2-16.5) ve MgO (%3.6-3.8) içerdikleri gözlenmektedir. Tüm
kil örneklerinin kızdırma kayıplarının (%14.2-17.7) yüksek olduğu
belirlenmiştir. Endüstriyel uygunluk değerlendirilmeleri kırmızı killerin yaygın
tuğla imalatı için yeterli özelliklere sahip olduğunu göstermektedir. Bununla
birlikte, marnlı killer ise ince cidarlı delikli ürünlerin imalatı için yeterli
özelliklere sahip olup, bazı değişikliklerle yaygın tuğla imalatında da
kullanılabilirler.

Characteristics of clays from Pamukkale (Denizli) region and their usability in ceramic sector

Abstract

X-Ray
fluorescence, thermal analyses, X-Ray diffractions, Attenberg limits, and
particle size analyses are used to determine mineralogical, physico-chemical,
and thermal properties of three clays from the Asartepe (LE2) and Kızılburun
(LE3 and LE4) formations from northeastern of the Pamukkale (Denizli) region. There
are no significant differences between the samples with respect to their chemical
and mineralogical compositions. Mineralogically, red clays (LE2) comprise mainly
quartz and small amount hematite, illite as clay minerals, and chlorite, kaolinite
and chlorite/smectite as minor clay minerals. Marl clays (LE3 and LE4) were
also rich in quartz, calcite, and pyroxene minerals, illite and a small amount
of chlorite, kaolinite and chlorite/smectite as clay minerals. Chemically, red clays consist of high amount of SiO₂
(52.0%), Fe₂O₃ (7.7%) and Al₂O₃
(19.2%) and marly clays have also lower SiO₂ (40.1-44.5%), Al₂O₃
(12.7-14.0%), and higher CaO (13.2-16.5) and MgO (3.6-3.8%) compositions. LOI (14.2-17.7%)
contents of the all clay samples are high. As a result, in industrial
suitability point of view, characteristics of red clays are suitable for common
brick manufacturing. However, marly clays have favourable properties for thin-walled
hollow brick production and can be used for manufacturing of common brick with
some modification.
