Celtra Ceram is a low-fusing, leucite-reinforced feldspathic veneering ceramic designed for layering lithium silicate frameworks (including Celtra Press) and zirconia frameworks (including Cercon ht and Cercon xt). The material features optimized bonding to lithium silicate without requiring a wash firing, high color stability across multiple firings, and natural esthetic results. 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 for first dentin layer, 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.
