Abstract
Spray drying banyak diaplikasikan di bidang industri untuk
mengeringkan material karena memiliki berbagai keuntungan
diantaranya mampu menghasilkan partikel hingga ukuran
nanometer, proses kontinyu, kemurnian serta kristalinitas produk
yang tinggi.Pada penelitian ini mencoba menggunakan Flame
Spray Drying untuk mengeringkan partikel. Model yang
digunakan pada penelitian ini adalah Sol Silika dan Slurry ZnO.
Peralatan utama yang digunakan pada eksperimen berupa
ultrasonic nebulizer, burner serta electrostatic precipitator.
Analisa SEM (Scanning Electromagnetic Microscope) , XRD (XRay
Diffraction) dan BET (Brunaur-Emmet-Teller) dilakukan
untuk mengetahui morfologi, kristalinitas, ukuran dan juga luas
permukaan dari partikel yang telah diperoleh. Morfologi dari
silika sendiri berbentuk bulat kecil. Silika memiliki struktur amorf
sehingga silika dapat digunakan sebagai material komposit karena
tidak mempengaruhi material utama. Dari penelitian ini dapat
disimpulkan bahwa untuk Slurry ZnO, semakin tinggi pH maka
semakin besar ukuran kristal partikel, semakin tinggi tekanan
maka semakin besar ukuran kristal partikel, dan morfologi dari
ZnO berbentuk seperti jarum. ========== Spray drying widely applied in industry for drying the material
because it has many advantages including particles capable of
producing up to nanometer size, a continuous process, product
purity and high crystallinity. In this study tries to use Flame
Spray Drying to dry particles. The model used in this study is Sol
Silica and Slurry ZnO.Major equipment used in this experiment
are an ultrasonic nebulizer, burners and electrostatic
precipitators. Analysis of SEM (Scanning Electromagnetic
Microscope), XRD (X-Ray Diffraction) and BET (Brunaur-
Emmett-Teller) was conducted to determine the morphology,
crystallinity, size and surface area of the particles that have been
obtained. Morphology of silica is small spherical. Silica has an
amorphous structure that silica can be used as a composite
material because it does not affect the main material. From this
study it can be concluded that for ZnO slurry, the higher the pH,
the greater the size of the crystal particles, the higher the
pressure, the greater the size of the crystal particles, and the
morphology of needle-shaped ZnO
