Silicon Nitride Bonded Silicon Carbide Polygonal Kiln Shelves
These custom NSiC kiln shelves are specifically developed for top-loading electric kilns. Compared to traditional silicon carbide kiln furniture, they are half the weight and twice as strong, with no deformation during high-temperature firing. Their modular design allows for flexible adaptation to the firing needs of different kilns.
Product Core Positioning
The polygonal/round kiln shelves launched by Starny Ceramics are an optimized kiln furniture solution specifically for top-loading electric kilns. They are primarily made from silicon nitride bonded silicon carbide (NSiC) composite material. Compared to conventional high-temperature silicon carbide shelves, they achieve a dual breakthrough in lightweight design and structural stability, maintaining flatness without warping or cracking even after multiple firings at 2600°F.
This kiln furniture belongs to the Starny high-end series. The design's original intention focuses on improving kiln space utilization, increasing firing capacity, and reducing energy consumption. By assembling multiple pieces to form a complete firing surface, it perfectly matches the diverse needs of small-batch prototyping in ceramic studios and large-scale production in industrial kilns.
Core Material and Performance
This series of kiln shelves is made from high-purity silicon nitride bonded silicon carbide as the core base material, formed by a special sintering process. It boasts industry-leading high-temperature resistance, with continuous working temperatures up to 2600°F, maintaining dimensional accuracy and stable physical properties in high-temperature environments.
The product's mechanical strength is 19 times that of traditional 1-inch thick silicon carbide shelves, yet its overall weight is reduced by 50%. While ensuring the load-bearing capacity of the kiln furniture, it significantly reduces the kiln's operating load, directly lowering electricity consumption and carbon emissions.
Four Core Values
Efficient Space Utilization
Modular, compact design maximizes internal kiln space layout, increasing single load capacity by over 15% and effectively reducing empty kiln firing rates.
Enhanced Production Efficiency
Strong high-temperature stability reduces deformation and cracking losses during ceramic firing, indirectly improving overall yield and production efficiency.
Guaranteed Firing Quality
High flatness of the shelf surface and uniform heat transfer ensure consistent heating of ceramic products, improving the uniformity of finished product color and texture.
Green and Low-Carbon Operation
Lightweight design reduces heat loss and lowers energy consumption for kiln heating. Long-term use can significantly reduce carbon emissions, complying with environmentally friendly production standards.
