Silicon nitride (Si3
N4
) SNA, SNB, SNC and SND were synthesized by hydrothermal
process at temperature of 100o
C, 150o
C, 200o
C and 300o
C using Rice Husk Ash (RHA) and
Sugarcane Bagasse Ash (SBA) respectively. The percentage of silica ranges from 90.10 to
94.19 with minute impurities.Based on their infrared spectra, for SNA absorption band
at 470.6 cm-1 is attributed to Si-N (stretching), which were also observed with SNB, SNC
and SND, a weak band at 671.2 cm-1 which is characteristic of a silicon nitride Si-N-Si
stretching vibration was observed, for SNC, peak at 574 cm-1 attribute to α-silicon nitride,
as temperature increases the spectrum becomes sharper. X-ray diffraction pattern indicates
that SNA material contained 64.6% α-phase and 27.8% β-phase silicon nitride. Therefore,
rice husks and sugarcane bagasse have great potential as a raw material for producing Si3
N4
