Kiln Shelves

Silicon Carbide Kiln Shelves

Kiln shelves are essential load-bearing components in kiln furniture systems. Silicon carbide (SiC) kiln shelves feature outstanding high-temperature strength and maintain structural stability at firing temperatures above 1,300°C—resisting warping, deformation, and cracking. Excellent thermal shock resistance and high load-bearing capacity make them a preferred choice for ceramic production.

▏How to Choose the Right Silicon Carbide Kiln Shelves？

• Standard Silicon Carbide

A cost-effective option for standard ceramic firing conditions. It is widely used for routine production where balanced performance and practical pricing are the priorities.
Best for: general ceramic

• Reaction-Bonded Silicon Carbide (RBSiC / SiSiC)

Higher strength and dimensional stability for demanding load conditions. Available in thinner options down to 2.5 mm, designed for long service life and low residue under proper firing conditions.

Best for: High-end porcelain production, including bone china, with high requirements for stability and surface cleanliness.

• Nano Silicon Carbide (Alumina-free surface)

Higher strength and dimensional stability for demanding load conditions. Available in thinner options down to 2.5 mm, designed for long service life and low residue under proper firing conditions.

Best for: High-end porcelain production, including bone china, with high requirements for stability and surface cleanliness.

• Pressureless-Sintered Silicon Carbide (SSiC, Alumina-free surface option)

SSiC is commonly selected for for stable, repeatable firing that demand higher material consistency and a cleaner surface. Alumina-free surface option is widely used for decal firing and other cleanliness-sensitive decoration processes..

Best for: Decal firing (ceramic decal applications) and other cleanliness-sensitive decoration processes requiring high stability and a clean surface.

Not sure which grade fits your production? Share your kiln type, firing temperature, and product type—we’ll recommend the most suitable solution.

Mullite-Based Kiln Shelves

Mullite kiln shelves are a reliable option for many standard ceramic firing applications. They offer good high-temperature stability and steady performance under routine firing cycles, making them suitable for general production needs. For more demanding conditions—such as higher temperatures or heavier loads—SiC or alumina-based kiln furniture is often preferred.

Speculations and Options

Grades: Mullite-based shelves / Cordierite–Mullite composition available on request

Max Temperature: Up to 1350°C (varies by grade and firing conditions)

Common Sizes: 370 × 550 mm; Custom sizes available

Thickness Options: Multiple thickness options available

Kiln Type: Roller Kiln / Tunnel Kiln / Shuttle Kiln

Lead Time: 7–14 Working days (subject to quantity and customization)

Packaging: Wooden crates + EPS foam inserts + bubble wrap
