Ceramic Furnace Plates

Ceramic Furnace Plates are rigid kiln-furniture components used to support, separate, and position workpieces during firing, sintering, heat treatment, and other high-temperature processes. Mullite, alumina, and high-purity alumina can be selected according to operating temperature, load, atmosphere, plate dimensions, and thermal cycling.
Standard and custom plates are supplied for wholesalers, distributors, importers, and furnace OEMs, with sizes, thicknesses, holes, grooves, and other features manufactured to approved drawings. 

High-Temperature Stability
Alumina and mullite maintain structural stability at elevated temperatures where conventional metal fixtures may soften or oxidize. Depending on grade, plates can be designed for applications around 1200–1800°C. Actual service temperature depends on material grade, load, atmosphere, geometry, and firing cycle.
Controlled Thermal Expansion
Mullite is commonly selected for its relatively low thermal expansion, while alumina offers a combination of high-temperature capability and mechanical strength. Matching the ceramic grade to the heating cycle helps reduce thermal stress and dimensional change.
Load-Bearing Performance
Plate performance depends on thickness, unsupported span, support spacing, workpiece weight, temperature, and load distribution-not room-temperature strength alone. These factors should be reviewed before selecting the plate specification.
Chemical Resistance
Dense alumina ceramic provides good resistance to many furnace environments and abrasive contact, making it suitable for repeated high-temperature support applications.
Custom Manufacturing
Square, rectangular, circular, and irregular plates can be produced. Holes, slots, grooves, chamfers, and edge finishing are available according to drawings or samples. 

Typical engineering ranges only. Final values are confirmed for the selected material grade and application.

Mullite: Suitable where relatively low thermal expansion and thermal-cycling stability are important.
Alumina: Selected when higher-temperature capability, mechanical strength, and chemical resistance are priorities.
High-Purity Alumina: Used for demanding high-temperature or chemically sensitive applications where higher alumina purity is required. 

Production can include powder preparation, forming, drying, high-temperature sintering, cutting, machining, and final inspection. Manufacturing and inspection can cover dimensions, thickness, flatness, hole position, surface condition, and specified material properties.
For repeat orders, approved drawings, material grades, production procedures, and inspection requirements can be retained to improve batch-to-batch consistency. Material test reports and dimensional inspection records can be provided when required. 

Custom production is available for distributors, importers, furnace manufacturers, and industrial users. Drawing-based production, sample evaluation, repeat orders, bulk manufacturing, and export packaging can be arranged according to project requirements.
