Premium Talc Powder Manufacturers in India
Talc powder is magnesium silicate used in ceramic manufacturing for its unique physical and mechanical properties. As trusted talc powder manufacturers in India, Expolica Ceramics delivers consistent quality material. Talc (3MgO.4SiO2.H2O) is used in small quantities (2-6%) in vitrified tile body composition to enhance the fluxing action of feldspathic materials reducing firing temperatures and shortening firing cycles, helping reduce energy costs.
- Efficient Fluxing Agent
- Improved Purity
- Thermal Shock Resistance
- Dimensional Stability
For Ceramic Manufacturing
Trusted Talc Suppliers in India
Expolica Ceramics extracts premium talc from dedicated mineral deposits across our five mines. As reliable soapstone powder suppliers, we deliver consistent magnesium silicate content with controlled particle fineness for vitrified tiles, sanitaryware, and technical ceramics production.
- High Magnesium Oxide : Our talc maintains MgO content between 30-32%, critical for effective fluxing action in ceramic formulations. This high magnesium level accelerates early vitrification, reducing required firing temperatures by 30-50°C.
- Micronized Particle Processing: We process talc to achieve particle sizes ranging from 200 mesh to 400 mesh depending on application requirements. Finer particles distribute more uniformly throughout ceramic bodies, improving flux effectiveness and surface smoothness.
- Controlled Loss on Ignition:Loss on ignition remains consistently between 5.5-6.5% in our talc, indicating proper hydration levels and minimal organic contamination. Stable LOI values mean predictable behavior during firing with no unexpected gas release causing bloating or pinholing.
- Low Iron for Whiteness Retention: Iron oxide content stays below 0.3% through selective mining from pure talc seams and magnetic separation processing. Minimal iron prevents yellowing or brown discoloration in fired ceramics.
- Enhanced Thermal Expansion : Our talc's specific mineral composition provides thermal expansion coefficients matching common ceramic bodies, reducing stress between glaze and body during cooling.
- Hydrophobic Surface Properties : Talc's natural hydrophobic characteristics improve slip casting behavior by reducing water absorption into molds and speeding release times. This property also benefits pressing operations by improving powder flowability.
