α-상 과 β-상 두 가지 종류의 탄화규소(SiC) 입자 표면에 수열 합성 방법으로 ZSM-5 결정을 형성하였다. SiC는 50 μm 이상이 되는 크기의 입자를 사용하였으며, ZSM-5 결정이 SiC 표면에서부터 성장하도록 유도하기 위하여 합성 단계에 앞서 SiC 표면에 산화층을 형성하였으며, 수열합성 온도와 시간을 변화시켜 보았다. 그 결과 β-SiC는 900 °C 조건에서도 산화막이 형성되었으며, 특히 150 °C 합성 조건에서 ZSM-5가 β-SiC 표면에서부터 성장하였음이 뚜렷이 관찰되었다. 200 °C 조건에서는 ZSM-5의 결정의 크기가 성장할 뿐 아니라, 시간의 증가에 따라 결정의 형태가 뚜렷해지고 SiC 표면에 도포되는 양이 증가하는 것을 확인할 수 있었다.

ZSM-5 crystals grew on the surface of α-SiC and β-SiC particles by hydrothermal synthesis method. SiC particles which were > 50 μm of size were used, and oxide layer were developed on the surface of the particles to induce growth of ZSM-5 from the surface. Then, synthesis time and temperature condition were considered growing ZSM-5. In this study, oxide layer was formed on β-SiC at 900 °C in air, and it was controlled to grow ZSM-5 grew from the β-SiC_x000D_ surface with 150 °C synthesis condition. This is due to Si-O-Si or Si-O-Al bond, which is basic framework of ZSM-5 can be easily formed, from the silicon oxide film on the surface of β-SiC. When the synthesis temperature was 200 °C, the size of ZSM-5 was increased, and it covered much area of the SiC surface with better crystal shapes with longer synthesis time.
