Quartz Ceramic Material Machining
Quartz ceramic material can be machined in its green or bisque state before sintering, making it easier to shape into complex forms. Like other ceramics, it shrinks by about 15–20% during sintering, so this must be considered in the initial design. After sintering, quartz ceramic becomes extremely hard and brittle, making machining very difficult and requiring diamond-coated tools and high-precision equipment.
Machining Methods and Considerations
- Green or Bisque Machining: Quartz ceramic is easier to cut and shape before sintering, making it suitable for intricate designs.
- Sintering Shrinkage: Expect a 15–20% size reduction during sintering, which affects dimensional accuracy.
- Post-Sintering Machining: After sintering, quartz becomes hard and brittle, requiring diamond tools and precise control.
- Fragility: Fully sintered quartz ceramic is prone to chipping or cracking if mishandled.
- Tooling and Time: Machining sintered quartz is slow and requires specialized equipment.
Quartz Ceramic Packaging
Quartz ceramic products are typically packaged in vacuum-sealed bags to prevent moisture or contamination and wrapped with foam to cushion vibrations and impacts during transport, ensuring the quality of products in their original condition.
