In the last few years, there has not been much research on green nanofluids that come from material resources such as parts of palm oil and natural zircon sand. Green need to be developed improve heat transfer performance. The characterization nanoparticles made synthesis process stability ZrO2-SiO2 Nanofluids-W/EG, different volume concentrations were investigated. experiments carried out using SEM FTIR, nanofluid was investigated for a concentration 0.1-0.3%, UV-Vis, Zeta potential sedimentation observation. results show size Nano-Zircon particles 32.984-38.465 nm Silicate with 44.002-50.444 nm. Nanofluids-W/EG UV-Vis method is stable up 30 days after preparation sonication time 2 hours value 70-80%. zeta evaluation performed obtained 45.37 mV good classification. Sedimentation this visual observation absence agglomeration days.
