Celtra Ceram is a low-fusing, leucite-reinforced feldspathic veneering ceramic designed for all-ceramic frameworks including lithium silicate (Celtra Press) and zirconia (Cercon ht, Cercon xt). The ceramic offers high aesthetic layering with natural optics, optimized bonding to lithium silicate frameworks without wash firing, and stable results even after multiple firings. Features include a coefficient of thermal expansion of 9.0 ± 0.5 x 10⁻⁶K⁻¹, 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.
