Talc-based ceramics, often used in machinable ceramic products like steatite and cordierite, are known for their thermal shock resistance, electrical insulation, and ease of machining. These ceramics are ideal for applications requiring moderate strength, good dielectric performance, and high dimensional stability—particularly in electrical, thermal, and prototyping environments.
Talc ceramics are magnesium silicate-based ceramic materials that are commonly used in the form of steatite, cordierite, or engineered machinable ceramics. These materials feature good thermal stability, low thermal expansion, and moderate mechanical properties, making them suitable for low-stress insulating and thermal cycling applications.
We offer CNC machining for high-purity sintered Talc Ceramic.

Challenges & Solutions
Talc ceramics are more forgiving to machine than dense ceramics like zirconia or silicon carbide, but care must still be taken to avoid micro-fractures in complex shapes.
Tolerances Achievable for Machined Talc Ceramics
Talc ceramics are preferred where insulation, low-cost machining, and thermal reliability are more important than extreme strength.
