Products classified under HTS 2842.10.00.00
Sodium Aluminosilicate Zeolite A
Sodium aluminosilicate, known as Zeolite A, is a synthetic aluminosilicate used primarily as a detergent builder and water softener. It falls under HTS 2842.10.00.00 as a chemically defined double or complex silicate. This microporous crystalline structure exchanges calcium ions for sodium ions in laundry applications.
Synthetic Zeolite 4A Powder
Zeolite 4A is a hydrated sodium calcium aluminosilicate powder used in molecular sieves and ion exchange applications. Classified under HTS 2842.10.00.00 as a double or complex aluminosilicate. Its specific pore size of 4 angstroms enables selective adsorption in industrial processes.
Hydrated Aluminosilicate Catalyst
Hydrated aluminosilicates serve as cracking catalysts in petroleum refining, featuring specific Si/Al ratios. This chemically defined complex silicate qualifies for HTS 2842.10.00.00. The material's acidity and structure enable hydrocarbon breaking in FCC units.
Mordenite Aluminosilicate Powder
Mordenite is a high-silica aluminosilicate zeolite used in gas separation and purification. Falls under HTS 2842.10.00.00 as a defined complex silicate structure. Its two-dimensional pore system provides shape-selective catalysis properties.
ZSM-5 Zeolite Catalyst Base
ZSM-5 is a medium-pore aluminosilicate zeolite with MFI framework topology used in methanol-to-gasoline processes. Classified in HTS 2842.10.00.00 as chemically defined complex silicate. Its intersecting 10-ring channels enable selective conversion.
Beta Zeolite Powder
Beta zeolite (*BEA topology) is a large-pore aluminosilicate used in hydrocracking and dewaxing catalysts. HTS 2842.10.00.00 covers this chemically defined double silicate. Its three-dimensional 12-ring pore system handles bulky molecules.
Y-Type Faujasite Zeolite
Y-faujasite zeolite (FAU framework) is ultrastable synthetic aluminosilicate for fluid catalytic cracking. Falls under HTS 2842.10.00.00 as defined aluminosilicate. High silica content provides thermal stability up to 800°C.
Silicalite-1 Aluminosilicate
Silicalite-1 (pure silica MFI) with trace aluminum forms hydrophobic zeolite membranes. Classified HTS 2842.10.00.00 when chemically defined as complex silicate. Used in pervaporation and organic separations.
Linde Type A Zeolite
Linde Type A zeolite is synthetic sodium aluminosilicate with 4Å pores for drying and purification. HTS 2842.10.00.00 applies to this defined double silicate. Standard in commercial molecular sieve products.
