Soapstone, talc, and high-purity quartz delivering exceptional dielectric properties, thermal stability, and chemical inertness for electrical applications.
The electrical industry demands minerals with exceptional dielectric properties, thermal stability, and chemical inertness. Soapstone (steatite) has been the material of choice for electrical insulators for over a century, while talc and quartz serve critical roles in cable insulation and electronic components.
From high-frequency insulators to semiconductor-grade silica, each mineral is selected and processed for critical electrical applications.
The premier material for high-frequency electrical insulators. Fired steatite ceramics deliver outstanding dielectric strength (>10 kV/mm), low dielectric loss factor, excellent thermal shock resistance, and mechanical strength exceeding 100 MPa. Composition: 90–95% talc (Mg₃Si₄O₁₀(OH)₂), fired at 1300–1400°C to form enstatite/clinoenstatite.
Filler in PVC and PE cable insulation compounds, providing electrical insulation, cost reduction, and improved fire retardancy. Enhances volume resistivity of insulation compounds for reliable power distribution and wiring systems.
High-purity quartz and fused silica for the most demanding electronic and semiconductor applications. SiO₂ content exceeding 99% for electronic grades, used in substrates, crucibles, and potting compounds where absolute chemical purity is non-negotiable.
