Celtra Ceram is a low-fusing, leucite-reinforced feldspar veneering ceramic designed for lithium silicate frameworks (including Celtra Press) and zirconia restorations (including Cercon ht and Cercon xt). The material offers highly aesthetic layering with natural optical properties, optimized bonding to lithium silicate without requiring a wash firing, and stable results even after multiple firings. Technical specifications include a coefficient of thermal expansion of 9.0 ± 0.5 x 10⁻⁶K⁻¹ (25–500°C), firing temperature of 770°C, glass transformation temperature of 520°C, flexural strength of 108 N/mm², and chemical solubility of 28 µg/cm². Package contains 1 jar of 15g.
