White Fused Alumina (WFA) is derived from calcined alumina using a specific electro fusion process, resulting in a highly pure and durable abrasive and refractory material. It features high chemical stability and high melting point which makes it a material of choice for high-performance applications.

Physical Characteristics

• Color: Pure white, indicating the absence of impurities.
• Density: 3.50 – 3.55 g/cm³, ideal for abrasive and refractory applications.
• Melting Point: Approximately 2250°C, suitable for high-temperature applications.
• Grain Shape: Predominantly angular, providing sharp cutting edges for abrasive applications
• Hardness: 9 on the Mohs scale, comparable to corundum.

Production Process

• Synthesis: Produced by the controlled fusion of high-purity alumina in an electric arc furnace.
• Processing: Includes cooling, crushing, magnetic separation to remove residual iron, and precise sieving to achieve desired grain sizes. Granular Size Specification

Granular Size Specification

• Micro Grits: Specifically designed for precision applications, available in FEPA sizes from F230 to F1200.
• Macro Grits: Ranging from F10 to F220, suitable for abrasive and refractory applications.
• Custom Sizes: Tailored to customer specifications including specific mesh Sizes for special applications.
• Grain Shape: Predominantly angular, providing sharp cutting edges for abrasive applications
• Hardness: 9 on the Mohs scale, comparable to corundum.

Extensive Applications

• Abrasives Industry: Utilized in bonded abrasives (grinding wheels, cutting discs) and coated abrasives (sandpaper, abrasive cloths).
• Refractories: Key material in the production of refractory bricks, castables, and mortars due to its high melting point and chemical inertness
• Ceramic Production: Used in the manufacture of high-grade ceramic products, including insulators and laboratory equipment.
• Surface Treatment: Preferred media for high-purity blasting applications and surface preparation tasks.
• Polishing Media: Employed in the production of polishing compounds for electronics, automotive, and optical materials.
• Composite Materials: Incorporated in composite coatings for wear and corrosion protection
• Other Advanced Applications: Used in filtration systems, biomedical materials, and as a raw material in the synthesis of advanced ceramics.

Chamotte is a calcined clay. The calcination process takes place in a rotary kiln at high temperatures of 1400 - 1600ºC. Sanitaryware pieces are fired at lower temperatures of around 1200ºC, therefore the chamotte is inert at the firing stage and acts like a skeleton to produce ware with better proprieties. Grog is composed of 40% minimum alumina, 30% minimum silica, 4% maximum iron(III) oxide, up to 2% calcium oxide and magnesium oxide combined. Its melting point is approximately 1, 780 °C (3, 240 °F). Its boiling point is over 9, 000 °C (16, 230 °F). Its water absorption is maximum 7%. Its thermal expansion coefficient is 5.2 mm/m and thermal conductivity is 0.8 W/(m•K) at 100 °C and 1.0 W/(m•K) at 1000 °C.
