High-Quality Feldspar

Processed & Supplied by SparkGuys

Feldspar is a group of alumino-silicate minerals containing potassium, sodium, and calcium. It is widely used as a functional raw material in numerous industrial applications. At SparkGuys, we source high-quality feldspar from trusted domestic mines and process it to meet the stringent requirements of various industries. Our in-house processing includes crushing, washing, drying, grinding, and magnetic separation to ensure a consistent, impurity-free product.

Key Features:

• High Alkali Content (K₂O or Na₂O)
• Low Iron & Titanium Impurities
• Good Melting Properties
• Stable Thermal Expansion Behavior
• Customizable Particle Sizes (from lumps to fine powder)

Types Offered:

• Potassium Feldspar (K-Feldspar)
• Sodium Feldspar (Na-Feldspar)
• Mixed Feldspar (as per customer specifications)

Industrial Applications:

• Ceramics & Tiles Industry Acts as a flux to lower the melting temperature of ceramic mixtures. Improves strength, durability, and vitrification of tiles, sanitaryware, and porcelain.
• Glass Manufacturing
  Provides alumina content that enhances the hardness, durability, and chemical resistance of glass.
  Used in the production of container glass, sheet glass, and fiberglass.
• Paints & Coatings
  Serves as a functional filler for enhancing durability, brightness, and resistance to chemical and weathering effects.
• Electrodes & Welding Rods
  Used as a fluxing agent in the coating of welding electrodes to stabilize arc and reduce spatter.
• Rubber & Plastics
  Acts as a reinforcing filler to improve mechanical strength and heat resistance in rubber and plastic compounds.
• Adhesives & Sealants
  Improves bonding strength and surface finish while enhancing rheological properties.
• Abrasives Industry
  Ground feldspar is used in polishing compounds and scouring cleansers due to its mild abrasive nature.
• Construction Chemicals
  Used in wall putties, grouts, and tile adhesives for its binding and setting properties.
