This product is a round, dense corundum/alumina honeycomb ceramic made for high-strength, high-temperature burner and decorative heating parts. The dense alumina body gives it a smooth, low-absorption surface suitable for visible gas-burner faces, fireplace circles, patio/garden heaters and round industrial heater heads. Because it is round, it can be dropped directly into cylindrical housings without extra machining.
With corundum-level refractoriness (up to about 1300 °C) and good compressive strength, it is a reliable B2B option for OEM burner and heating-equipment manufacturers.

Round gas/IR burner faces for catering stoves, ceramic cookers, patio heaters and outdoor flame features.
Decorative circular fireplace inlets where the customer wants a ceramic, not metal, hot-face.
Industrial or lab hot-air outlets that use round ducts and need a heat-resistant honeycomb at the end.
Energy-saving burner retrofits replacing metal mesh with a corundum honeycomb to improve flame diffusion.
Brandable heater fronts — surface can be supplied for coloring/glazing so OEMs can make differentiated heating products.
Q1: Can the round panel be supplied without a center hole or slots?
Yes. We can supply full discs, or we can pre-cut slots/notches to match your burner frame.
Q2: Will it crack if the burner is turned on and off many times a day?
No. The corundum body is designed for ≈200 K thermal-shock resistance, which suits frequent ignition cycles.
Q3: Can you match a special diameter for our existing metal housing?
Yes. Tell us the inner diameter and allowable thickness, and we will produce a matching round honeycomb.
Q4: Is the surface suitable for colored or matte decorative coatings?
Yes, the dense alumina surface can accept high-temperature decorative layers—just tell us the working temperature.
Q5: Do you supply long-term OEM quantities?
Yes. Hunan Zhonghong New Material can deliver stable batches for burner, fireplace and heater manufacturers.
