SSZ-13

[2] The framework topology is the same as that of chabazite but SSZ-13 has a high silica composition with Si/Al > 5, which leads to low cation exchange capacity.

[1] The material was patented by Chevron research Company in 1985,[3] and could potentially be used as a solid catalyst for the methanol-to-olefins (MTO) process and the selective catalytic reduction (SCR) of NOx.

Lattice constants vary depending on the Si/Al ratio and the metal species contained, but the symmetry of the crystal remains basically the same.

The resulting viscous gel is aged for two hours and heated for 4 days at 160 °C in a Teflon lined steel autoclave.

Submicron-sized SSZ-13 can be prepared in 6 hours through a rapid steam-assisted crystallization method using tetraethyl orthosilicate (TEOS) as the silica source.
