Feldspar is the most abundant mineral group on earth, and in industrial manufacturing, it is one of the most critical raw materials. Feldspar acts as a fluxing agent in ceramic and glass bodies — lowering the melting temperature of the batch, promoting vitrification, and creating a dense, glassy matrix that gives finished products their strength, whiteness, translucency, and surface quality.

In the ceramic industry, feldspar typically constitutes 20–35% of a tile body and 15–30% of a sanitaryware or porcelain slip. In glaze and frit formulations, feldspar is the primary source of alkali oxides — K₂O (potassium oxide) and Na₂O (sodium oxide) — that drive fusion and surface smoothness.

There are two primary commercial types of feldspar used in industry:

• Potash Feldspar (Potassium Feldspar / K-Feldspar) — Rich in K₂O; preferred for porcelain, vitrified tiles, bone china, and high-temperature applications where a harder, more viscous melt is needed.

• Soda Feldspar (Sodium Feldspar / Na-Feldspar / Albite) — Rich in Na₂O; preferred for wall tiles, floor tiles, sanitaryware, and frit where a lower melting temperature and more fluid melt is advantageous.

Our potash feldspar (also called potassium feldspar, K-spar, or orthoclase feldspar) is processed from carefully selected pegmatite deposits. The mineral undergoes beneficiation, crushing, and precision milling to deliver consistent chemical and physical parameters batch after batch.

Why K₂O Matters in Your Ceramic Body

• Greater hardness and mechanical strength in the fired product

• Higher whiteness and brightness (L* value) due to purer crystal structure

• Lower tendency for warpage and dimensional distortion in floor and vitrified tile bodies

• Improved translucency in fine porcelain and bone china

• Stable vitrification range — forgiving in industrial tunnel kilns

Our soda feldspar (also called sodium feldspar, Na-feldspar, or albite) is the preferred choice for manufacturers requiring a lower-melting, more fluid flux that gives clean, bright, smooth surfaces — especially in wall tiles, floor tiles, sanitaryware slip, and frit manufacturing.

Why Na₂O Delivers Superior Surface Quality

• Lower firing temperature — energy savings in kiln operation

• More fluid melt — improved surface smoothness, reduced pinholes

• Better glaze integration — soda feldspar blends seamlessly into frit and glaze batches

• Excellent whiteness in the fired body — critical for sanitaryware and white wall tiles

• Reduced crawling and glaze defects in single-fire and double-fire processes
