Natrium Silikat didapat dari reaksi antara kaca dengan natrium karbonat pada suhu 900 o C. Pada penelitian ini dibuat 2 macam variasi. Pertama adalah variasi konsentrasi CTAB dan TMACl (0,2 M dan 0,1 M; 0,4 M dan 0,2 M; 0,6 M dan 0,3 M). Kedua adalah variasi pH (9, 10 dan 11). Sintesis dilakukan dengan mencampurkan larutan natrium silikat, TEOS, CTAB, TMACl dan akuades yang melalui proses hidrotermal dan kalsinasi. Karakterisasi hasil penelitian dilakukan dengan metode analisis XRD, FTIR, dan adsorpsi gas N 2 melalui persamaan BET Dari hasil analisis XRD dan FTIR menunjukkan bahwa material silika kristalin hasil sintesis merupakan jenis stishovit, kuarsa dan kristobalit yang belum murni. Ukuran pori rata-rata, luas permukaan spesifik dan volume total pori dari produk adalah 10,066 Å; 30,8292 m 2 /g dan 15,517 cm 3 /g untuk sampel dengan konsentrasi CTAB 0,4 M dan TMACl 0,2 M; 9,597 Å, 40,2642 m 2 /g dan 19,320 cm 3 /g untuk sampel dengan konsentrasi CTAB 0,6 M dan TMACl 0,3 M; 9,500 Å; 38,7657 m 2 /g dan 18,413 cm 3 /g untuk sampel dengan pH 10.}, issn = {2597-9914}, pages = {20--28} doi = {10.14710/jksa.11.1.20-28}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/15095} }
