Wollastonite (CAS NO : 13983-17-0)

The industrial mineral sector is currently witnessing a significant integration of high-aspect-ratio acicular wollastonite (CAS 13983-17-0) as a critical reinforcing agent in high-performance polymer composites, where its unique needle-like morphology and low coefficient of thermal expansion (CTE) are essential for achieving superior dimensional stability and flexural modulus in automotive and aerospace engineering plastics. Concurrently, the ceramic industry is optimising fluxing efficiencies by leveraging the low loss on ignition (LOI) and high brightness of premium-grade calcium metasilicate, which facilitates rapid-fire cycles and reduces thermal shrinkage in vitreous bodies and glazes while enhancing mechanical fracture toughness. Furthermore, the global shift towards sustainable construction is accelerating the adoption of ultrafine wollastonite as a bioactive and chemically inert substitute for hazardous fibres in fire-resistant boards and high-performance cementitious systems, capitalising on its ability to improve load-deflection response and alkaline resistance through synergistic mineral reinforcement.
