Description
High-melting micro-porcelain based on feldspar for all ZrO₂ frames.
Advantages:
- High bonding properties due to high-melting opaque liner;
- Continuous CTE, also after multiple firings;
- Natural aesthetics in an economical expenditure of time due to simple two-layer technique;
- Excellently antagonist-friendly.
Physical data:
- CTE 9.3 x 10⁻⁶K⁻¹ (25-500 °C); firing temperature 900-920 °C (1st body); glass transition temperature 605 °C (body); chemical solubility 14.8 µg/cm².
