Synthesis of a Si-Al gel as a starting material of aluminosilicate solids

Sato, Junya; Shiota, Kenji*; Takaoka, Masaki*

Zairyo, 70(5), p.406 - 411, 2021/05

An aluminosilicate solid is an inorganic material that has the property of immobilizing heavy metals or radionuclides in the matrix. In this study, aluminosilicates with a Si/Al molar ratio of 0.5 was synthesized from a chemical reagent in order to produce aluminosilicate solids with a low Si/Al molar ratio, which were expected to improve the immobilization of heavy metals and radionuclides contained in the matrix. The synthesized Si-Al gel with a Si/Al molar ratio of 0.5 had little impurity content and was in an amorphous phase. In addition, the compressive strength of the aluminosilicate solid produced by the synthesized Si-Al gel showed a 5 MPa or more, confirming that it can be used as a raw material for aluminosilicate solids. The aluminosilicate solid with a Si/Al molar ratio of 1.25 had a dense surface structure from the result of BSE images and had the highest compressive strength among all samples.

Journal of the American Ceramic Society, 88(2), p.459 - 461, 2005/02

 Times Cited Count:120 Percentile:99.19(Materials Science, Ceramics)

Single phase silicon carbide (SiC) nanotubes were succeeded in synthesized by the reaction of carbon nanotubes (CNTs) with Si powder at 1200 $$^{circ}$$C for 100 h. The X-ray diffraction patterns indicate that much CNTs reacted at 1200 $$^{circ}$$C for 100 h was transformed to SiC. The results of TEM observation reveal that not only the coexisted nanotubes with SiC and graphite phase but also single phase SiC nanotubes were synthesized by reacting for 100 h. The proportion of single phase SiC nanotubes to the coexisted nanotubes increased by heat treatment at 600 $$^{circ}$$C in air for 1 h since the remained carbon was removed.
