Abstract
Membran rapat asimetris CaTiO3 telah dibuat dari oksida
perovskit CaTiO3 tanpa retak. Tahapan yang dilakukan dalam
pembuatan membran rapat asimetris CaTiO3 yaitu sintesis oksida
perovskit CaTiO3 dengan metode solid state, metode inversi fasa
rendam-endap dengan polieterimida sebagai binder polimer, dan
tahap sintering. Suhu sintering sangat menentukan morfologi
akhir membran rapat asimetris. Suhu sintering yang digunakan
adalah 890°C, 1100°C dan 1200°C. Fasa kristal CaTiO3 dianalisa
menggunakan X-Ray Difraction (XRD), menunjukkan kesesuaian
dengan standard International Center Difraction Data. Foto
Scanning Electron Microscope (SEM) menunjukkan telah
terbentuk membran rapat asimetris dengan struktur pori fingerlike.

and
sintering technique. The final membrane morphology
depended by sintering temperature. Sintering temperature was
used 890°C, 1100°C, 1200°C. Crystal phase of CaTiO3
characterized with X-Ray Difraction (XRD) approach with
International Center Difraction Data. standart. Scanning
