EVOLUSI MIKROSTRUKTUR DARI KERAMIK PADUAN SILIKA (SiO2) DAN ALUMINA (Al2O3)
Abstract: The study on the
effect of sintering temperature on the microstructure of ceramic to microstructure
of silica (SiO 2 and alumina (Al 2 O 3 ) composite was successfully performed. The
microstructure from SEM photos of samples after sintering as well as their
crystallinity were studied. Sintering were performed by using electric furnace
(conventional) and 2.45 GHz microwave. The crystallinity was determined by
using X-Ray Diffraction (XRD). SEM photos shows that with the increasing of
sintering temperature, the porosity of samples decreased quickly, the density
and hardness also increased. There are differences of their properties between
conventional and microwaved sintered samples at same sintering temperature. XRD
graphs shows that the crystallinity of samples on sintering by using microwaves
higher than that of conventional heating.
