P3010 Potassium-Stabilized Silica Sol
P3010
Potassium-stabilized colloidal silica with 30±1% SiO₂, a standard particle-size range of 10–20 nm and alkaline pH of 9–10.
K₂O ≤0.3%
The published potassium oxide limit should be checked against the buyer's formulation and acceptance specification.
Particle Size
A customized particle size can be reviewed after the target value, tolerance, trial volume and annual demand are provided.
Confirm by Sample
Evaluate the selected specification under the buyer's actual formulation, processing and storage conditions before bulk purchasing.
Information Needed Before Quotation

Applications of Potassium Colloidal Silica
Potassium colloidal silica can be evaluated where an alkaline, potassium-stabilized silica dispersion is preferred. Compatibility should be confirmed under the actual formulation and processing conditions before bulk use.
Precision Casting
Evaluated as an inorganic binder in compatible investment-casting shell systems requiring a potassium-stabilized silica sol.
Refractory Materials
Used as a silica-based binder in selected refractory formulations after compatibility and processing trials.
High-Temperature Coatings
Suitable for formulation trials requiring an alkaline aqueous silica dispersion and inorganic binding characteristics.
Ceramic Materials
Evaluated as an inorganic binder or nano-silica component in compatible ceramic and composite formulations.
Catalyst and Adsorbent Systems
Can be assessed as a silica source or binder where potassium ions are compatible with the required composition.
Inorganic Binder Systems
Suitable for material-development projects requiring controlled silica content, alkaline pH or customized particle size.
