Karbon ve Boraks ile Modifiye Edilen Perlitin Karakterizasyonu ve Termal Davranışı

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

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.
