LUDOX® colloidal silicas have been used for many years to manufacture catalysts for fluid cracking, emissions control, and a variety of chemical syntheses. Most commonly, they offer excellent binding power and high temperature stability.
LUDOX® colloidal silica products are known for their consistent quality, narrow particle size distribution, purity and, in some grades, low sodium levels. LUDOX® colloidal silicas have a proven track record of high performance in many catalytic applications.
• Provide the silica component of the catalyst support, zeolite, or molecular sieve
• Bind the components of the catalyst together
• Improve adhesion to substrates
• Improve physical properties (hardness, attrition resistance, etc.)
• Stabilize catalytic activity
LUDOX® colloidal silicas offer highly pure silica with controlled size, making them an effective source of silica for zeolite synthesis. The colloidal silica particles are at least partially dissolved in the alkaline synthesis mix, and when combined with an alumina source, can crystallize into the desired aluminosilicate zeolite structures.
