K-feldspar (potassium feldspar) is sourced from many countries — India, Turkey, China, Brazil, and several others supply the global market. Our SY101 grade is a flotation-processed K-feldspar from premium Henan Province deposits, distinguished by its high combined K2O+Na2O content and consistent chemistry achieved through advanced flotation beneficiation. This page compares SY101 with K-feldspar from major international sources.
SY101 Processing Advantage: Flotation
SY101 is produced using froth flotation — a selective mineral separation process that uses chemical collectors to separate feldspar from quartz, mica, and iron-bearing gangue minerals. Flotation produces a purer feldspar concentrate with higher alkali content and lower impurities than simple crushing-and-grinding operations. Not all feldspar suppliers use flotation — many rely on basic crushing and magnetic separation, which cannot achieve the same purity level. When evaluating SY101 against alternatives, ask the competing supplier: do you use flotation processing?
Key Differentiators
Consistency: Flotation from a single large deposit provides stable chemistry between batches. Multi-source suppliers mixing feldspar from different mines introduce variability. Alkali content: SY101 delivers high combined K2O+Na2O from flotation concentration — your formulation gets maximum flux value per ton. Documentation: Every SY101 shipment includes COA with independent lab verification. Logistics: From our central China location, we ship to three major ports (Tianjin, Qingdao, Lianyungang) for competitive freight to any global destination.
Applications Where SY101 Excels
SY101 is specifically recommended for: sanitaryware bodies (where K2O high-viscosity melt prevents shape distortion); electrical porcelain (where consistent K2O content is critical for electrical properties); and glass production (where high alkali K-feldspar reduces soda ash requirements). For applications where you need K-feldspar specifically rather than nepheline, SY101 delivers flotation-grade quality at competitive international pricing.
