Abstract

 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
