Ceramic Firing Plate

Ceramic firing plates offer excellent heat resistance. They can withstand extremely high temperatures without deforming or cracking, making them suitable for use in kilns and furnaces.
These plates provide a stable and uniform surface for the objects being fired. Their even heat distribution helps ensure consistent results and reduces the risk of uneven heating or warping of the fired items.

Products Description

A ceramic firing plate is a critical auxiliary device used in high-temperature heat treatment processes. It is typically made from high-purity, refractory ceramic materials. Its primary function is to support the workpieces being sintered (such as ceramic green bodies, electronic components, powder metallurgy products, etc.), ensuring their stable placement inside the high-temperature furnace. Simultaneously, it prevents direct contact with the furnace chamber, thereby avoiding contamination, adhesion, or deformation.

Key Performance Characteristics

Excellent High-Temperature Stability: Capable of operating for extended periods under extreme temperatures well above 1000°C (commonly up to 1600°C or higher, depending on the material) without softening, melting, or significant deformation.
Superior Thermal Shock Resistance: Can withstand rapid heating and cooling cycles, resisting thermal stress caused by sudden temperature changes, and is less prone to cracking.
High Chemical Inertia: Does not react chemically with most workpieces and atmospheres (such as air, nitrogen, hydrogen, inert gases) at high temperatures, preventing contamination of the workpieces.
High Mechanical Strength and Hardness: Maintains sufficient structural strength at high temperatures to support workpieces, with good wear resistance and long service life.
Low Thermal Conductivity: Helps reduce uneven heat transfer, promoting uniform heating of the workpiece.
Flat and Smooth Surface: Ensures a level base for the workpiece and facilitates easy separation from the sintered product.

Primary Applications

Ceramic firing plates are widely used in industrial and research fields requiring high-temperature sintering, annealing, or heat treatment:

Advanced Ceramic Sintering: Used for sintering electronic ceramics (e.g., MLCCs, piezoelectric ceramics), structural ceramics (e.g., zirconia, silicon carbide), bioceramics, and other green bodies.
Powder Metallurgy: Supports compacts during the sintering process of metal or ceramic powders.
Semiconductor Industry: Used in processes such as wafer diffusion and annealing.
New Energy Sector: High-temperature sintering of lithium-ion battery cathode materials like lithium iron phosphate (LFP) and ternary materials.
Photovoltaic Industry: Firing of coated solar cells (e.g., PERC).
Phosphor and Ceramic Pigment Sintering: Requires a high-purity environment to prevent impurity introduction.
Laboratory Research: High-temperature synthesis and heat treatment experiments for various new materials.
Magnetic Material Sintering: Such as the preparation of ferrite materials.
