비이온성 계면활성제 수용액 중에서 $Na_2SiO_3$$H_2SiF_6$의 빠른 반응을 통하여 메조포러스 분자체를 제조하였다. 침전은 수초 이내에 형성되었으며, 시료의 XRD분석은 d-spacing이 3.1-5.8 nm인 잘 발달된 피크를 나타내어 메조포러스분자체임을 확인할 수 있었다. 비표면적은 비이온 계면활성제에 따라 $290-1,018m^2/g$의 큰 값을 나타내었으며, 기공분포는 2.5-3.1 nm의 일정한 값을 보여주었다. SEM을 통해 관찰한 입자의 모양은 크기가 ${\sim}0.5{\mu}m$로 균일하고 잘 분리된 구형이었으며, TEM은 기공의 형태가 일정크기의 벌레구멍 모양임을 보여주었다.
