- Product Introduction
Products Description
The D98mm Zirconia Block For dental Lab Use has a density ranging from 5.6–6.1 g/cm³, offering strong mechanical properties, a hardness of around 7.5, providing excellent wear resistance, a melting point of approximately 2,550°C (4,600°F), ensuring excellent stability in high-temperature environments, and a low thermal expansion coefficient (typically between 10–12 × 10⁻⁶/K), ensuring good dimensional stability at high temperatures.
When buying zirconia blocks, there are several key factors to pay attention to:
1. Purity
Whether the purity of the zirconia block meets your needs. High-purity zirconia has better physical and chemical stability and is more suitable.
2. Size and shape
Whether the size and shape meet your needs.
3. High temperature resistance
The performance of the zirconia block at the working temperature to avoid the degradation of the material due to excessive temperature.
4. Corrosion resistance
Whether the selected material has sufficient corrosion resistance.
