Bu makalede, Van Gölü Havzası'ndan elde edilen perlitin aktif karbon ve
boraks ile yapılan yüzey modifikasyonlarının perlitin ısıl davranışına etkisi
incelenmiştir. Elde edilen perlit yüzeyi aktif karbon ve boraks ile modifiye
edilmiştir. Böylece saf perlit, aktif karbon ile modifiye edilmiş perlit ve boraks
ile modifiye edilmiş perlit partiküllerinin termal ve yüzey özellikleri
araştırılmıştır. Elde edilen sonuçlara göre, saf perlitin yüzeyi karbon ile önemli
ölçüde değişmezken, boraks modifikasyonundan sonra saf perlitin yüzeyinin
açıkça değiştiği görülmüştür. 30-1000 ºC aralığında ki termogravimetrik analiz
sonuçlarına göre saf perlit, karbon kaplı perlit ve boraks kaplı perlit
partiküllerinin toplam kütle kayıpları sırasıyla; %3.153, %3.156 ve %1.191
olarak tespit edilmiştir. Bu sonuçlar değerlendirildiğinde, boraks
modifikasyonunun perlit partiküllerinin termal özelliklerini açıkça arttırdığını
göstermektedir.

Characterization and Thermal Behavior of Modified Perlite with Carbon and Borax

Öz

In this article, the effect of surface modifications made with activated
carbon and borax on the thermal behavior of perlite obtained from the Van Lake
Basin was investigated. The obtained perlite surface was modified with activated
carbon and borax. Thus, the thermal and surface properties of pure perlite,
activated carbon modified perlite and borax modified perlite particles were
investigated. According to the results obtained, the surface of pure perlite did not
change significantly with carbon, while the surface of pure perlite clearly changed
after borax modification. According to the results of thermogravimetric analysis
in the range of 30-1000 ºC, the total mass losses of pure perlite, carbon-coated
perlite and borax-coated perlite particles are respectively; It was determined as
3.153%, 3.156% and 1.191%. When these results are evaluated, it shows that the
borax modification clearly increases the thermal properties of the pearlite
particles.
