What is Neoceram?
Neoceram is a low-expansion lithium-aluminosilicate glass-ceramic (grades N-0 and N-11) produced by crystallizing a shaped glass precursor, in the same class as Ceran and Robax panels. It is chosen for flat panels that see repeated thermal cycling and local heating, with a 700 °C maximum service temperature and 1.65 W/m·K thermal conductivity, and is normally supplied as rolled and ceramized sheet cut to size. All geometry must be set before ceramming; afterwards only diamond grinding applies, and the material cannot be welded or cold-formed. Macor is the alternative when a machinable glass-ceramic is required. Neoceram has a density of 2.51 g/cm³ (0.0907 lb/in³), lighter than 70% of glass grades. It melts at 1,400°C (2,552 °F). Neoceram has a tensile strength of 50 MPa (7.25 ksi), stronger than 59% of glass grades. Elongation at break is 0% and the elastic modulus is 88 GPa (12.8 Msi).

Physical5
Neoceram has a density of 2.51 g/cm³ (0.0907 lb/in³), lighter than 70% of glass grades. It melts at 1,400°C (2,552 °F).
Mechanical12
Neoceram has a tensile strength of 50 MPa (7.25 ksi), stronger than 59% of glass grades. Elongation at break is 0% and the elastic modulus is 88 GPa (12.8 Msi).
Thermal5
Neoceram is rated for continuous service to 700°C (1,292 °F). It conducts heat at 1.7 W/m·K (0.953 BTU/hr·ft·°F), better than 64% of glass grades. Thermal expansion is 0.2 µm/m·K (0.111 µin/in·°F).
Electrical5
Neoceram is an electrical insulator with a dielectric strength of 20 kV/mm (508 V/mil) and a resistivity of 1×10¹¹ Ω·m.
Chemical & Environmental2
Corrosion resistance is excellent (90/100), better than 73% of glass grades.
Sustainability4
Producing a kilogram of Neoceram takes about 30 MJ of energy and emits 2.1 kg of CO₂ — less than 79% of glass grades. Typical recycled content is 5%.
Manufacturability3
Neoceram's machinability is not recommended (8/100, worse than 84% of glass grades).

Working with Neoceram
Is Neoceram easy to machine?
Grind, drill and edge only with diamond tooling and copious water; waterjet works but needs low pierce pressure — no conventional cutting or scoring after ceramming.
Can Neoceram be welded?
Not weldable; joined mechanically with gaskets/clips or by high-temperature silicone, glass frit or metal-to-glass sealing.
Can Neoceram be formed, bent or molded?
Shaped as a green (vitreous) precursor by rolling, pressing or slumping, then crystallized at ~800–950 °C; no post-ceramming forming is possible.

Neoceram — frequently asked
What is Neoceram used for?
Neoceram is typically used for cooktop panels, fireplace windows and fire-rated glazing. In short: cooktop-grade glass-ceramic; near-zero thermal expansion; 700 °C service panels.
What is the tensile strength of Neoceram?
Neoceram has a typical tensile strength of 50 MPa (7.25 ksi) — stronger than 59% of glass grades. Strength varies by condition: see the 2 listed tempers.
Is Neoceram easy to machine?
Not especially — machinability is rated not recommended (8/100, worse than 84% of glass grades). Grind, drill and edge only with diamond tooling and copious water; waterjet works but needs low pierce pressure — no conventional cutting or scoring after ceramming.
Can Neoceram be welded?
