Product Description

 

Ultra-White Calcined Talc is a high-grade ceramic-specific mineral filler processed from high-purity low-iron talc ore through multi-stage purification, fine wet grinding and precise low-temperature calcination. Tailored for the ceramic industry, it is widely used in the manufacturing of high frequency porcelain, radio electric porcelain, industrial ceramics, architectural ceramics, daily-use ceramics and various ceramic glazes. The core advantages lie in stable performance without discoloration at high firing temperature, significantly improved whiteness after calcination, uniform bulk density, excellent luster and smooth finished surface. With ultra-high whiteness, ultra-low iron content and stable thermal performance, it effectively upgrades the surface texture and yield rate of ceramic products, and can also be applied in high-end coatings, plastics and other industrial fields as a high-quality functional filler.

Core Advantages

 

• High Temperature Resistance & No Discoloration: Customized for ceramic high-temperature firing process. The powder maintains stable color and zero discoloration under extreme high-temperature conditions, avoiding color difference and stain defects of ceramic blanks and glazes, ensuring consistent batch color of finished ceramics.
• Firing Enhanced Whiteness & High Gloss: Adopts low-iron high-purity raw ore formula. The whiteness is further improved after high-temperature forging and burning, endowing ceramic products with pure white texture and bright luster, effectively improving the grade and ornamental value of ceramics.
• Uniform Density & Super Smooth Surface: Featuring ultra-fine particle size and narrow particle size distribution, the talc powder has excellent filling uniformity. It perfectly optimizes the flatness and smoothness of ceramic glaze surface, reduces surface roughness and improves product hand feel and finish.
• High Purity & Stable Ceramic Grade Quality: Strictly controlled low iron content (Fe2O3≤0.02%), asbestos-free and free of harmful heavy metals. With stable chemical composition, it avoids glaze pinholes, bubbles and cracking problems during ceramic firing, and greatly improves product yield.
• Good Thermal Stability & Process Adaptability: Possesses excellent thermal stability and structural stability, adapts to various ceramic firing processes. It can effectively reduce firing temperature, save production energy consumption, and improve the molding performance of ceramic blanks.
   

  

  

  
   

Application

 

• Ceramics Industry (Core Main Application): Specially developed for all kinds of ceramic production, including high frequency porcelain, radio electric porcelain, industrial ceramics, architectural ceramics and daily-use ceramics, as well as all types of ceramic glaze formulations. It features no discoloration at high temperature, enhanced whiteness after firing, uniform density, high luster and smooth surface. It solves common defects such as uneven glaze color, dark spots and rough surface, greatly improving the appearance quality, durability and market competitiveness of ceramic products.
• Coatings Industry (Auxiliary Application): Suitable for high-end water-based and oil-based architectural coatings and industrial paints. Its high whiteness and stable weather resistance enhance coating hiding power and surface flatness, prevent yellowing and aging of paint films.
• Plastics Industry (Auxiliary Application): Used as functional filler for modified plastics, improving product rigidity, heat resistance and dimensional stability, reducing molding shrinkage for high-quality plastic products.
• Rubber Industry (Auxiliary Application): Serves as reinforcing filler to optimize rubber processing performance, improve product hardness and wear resistance, and reduce production costs.
• Cosmetics & Daily Chemicals: Ultra-fine and safe powder grade, mild and non-irritating, applicable for high-end daily chemical and cosmetic powder products.
• Pharmaceutical & Food Industry: Compliant with international safety standards, available for safe filling and auxiliary processing of pharmaceutical and food-grade products.
