Abstract: The present disclosure provides a sound absorbing material. The sound absorbing material comprises MFI-structural-type zeolite. The MFI-structural-type zeolite comprises a framework, and the framework comprises SiO2 and AlO3, and the mass ratio of Si to Al in the framework is less than 200 and not less than 50. The present disclosure also provides a speaker box applying the sound absorbing material. The sound absorbing material provided by the present disclosure and the speaker box using the sound absorbing material can further improve the performance of the speaker box, reduce the failure of zeolite and improve the performance stability of the speaker box.

Abstract: The zeolite UTD-1 may be formed under hydrothermal synthesis conditions using a directing agent that does not include a metal atom therein. Methods for synthesizing the zeolite UTD-1 may comprise: combining at least a silicon atom source and a directing agent having a structure of in an aqueous medium; forming the zeolite in the aqueous medium under hydrothermal synthesis conditions, such that the zeolite has a framework silicate with a cationic portion of the directing agent occluded within pores or channels of the framework silicate; and isolating the zeolite from the aqueous medium. The zeolite has a powder x-ray diffraction pattern with at least the following 2θscattering angles: 6.0±0.12, 7.6±0.1, 14.66±0.15, 19.7±0.15, 21.27±0.15, 22.13±0.15, 22.61±0.15, and 24.42±0.10 for a borosilicate form zeolite, or 6.0±0.12, 7.6±0.15, 14.55±0.15, 19.64±0.15, 21.01±0.20, 21.90±0.20, 22.34±0.20, and 24.38 ±0.20 for an aluminosilicate form zeolite.

Abstract: A new crystalline aluminosilicate zeolite comprising a new framework has been synthesized that has been designated UZM-55. This zeolite is represented by the empirical formula: M+mRrAl1-xExSiyOz where M represents a metal or metals selected from zinc or Group 1 (IUPAC 1), Group 2 (IUPAC 2), Group 3 (IUPAC 3) or the lanthanide series of the periodic table including sodium, potassium or a combination of sodium and potassium cations, R is an organic structure directing agent or agents derived from reactants R1 and R2 such as where R1 is diisopropanolamine and R2 is a chelating diamine, and E is an element selected from the group consisting of gallium, iron, boron and mixtures thereof. Catalysts made from UZM-55 have utility in various hydrocarbon conversion reactions. The calcined zeolite is used in hydrocarbon conversion reactions.
