Kiln Furniture / Support Industrial Ceramic Materials
Last Updated: April 1, 2025
Description
Kiln furniture refers to the ceramic components used to support and hold products during the firing process in kilns. These components are designed to withstand high temperatures and provide structural support to the items being fired, ensuring they maintain their shape and integrity throughout the process.
Working Principle
Kiln furniture operates by providing a stable and heat-resistant platform for items within a kiln. Made from materials such as high-purity alumina, mullite, and silicon carbide, these components are engineered to endure the extreme temperatures of industrial kilns, which can exceed 2300°F . The high thermal conductivity and strength of these materials allow kiln furniture to efficiently transfer heat while maintaining structural integrity, thus optimizing the firing process and ensuring uniform heat distribution.
Applications
Kiln furniture is used in a variety of industrial applications. For example, in the production of tableware, sanitaryware, and porcelain, kiln furniture like Lo-Mass® components are employed due to their customizable and flexible nature . In heavy industrial applications, such as the production of high-voltage insulators, kiln furniture systems made from advanced materials like SiSiC and NSiC are utilized for their strength and lightweight properties .
Advantages over other Industrial Ceramic Materials
Kiln furniture made from advanced materials such as Lo-Mass® and Advancer® offers significant advantages over traditional ceramic materials. These include being thinner, lighter, and significantly stronger, which allows for reduced size and weight of the furniture, leading to greater kiln capacity and reduced firing cycles . Additionally, these materials provide high thermal conductivity, which enhances the efficiency of the firing process.
Limitations
One limitation of kiln furniture is the potential for warping or degradation over time due to repeated exposure to high temperatures. For example, in box kilns, the steel supporting structure can warp with use, leading to issues with the configuration of the kiln door and potential heat loss .
Considerations
When selecting kiln furniture, several factors should be considered, including initial costs, operating expenses, and durability. High-strength materials like those used in Lo-Mass® and Advancer® products may have higher initial costs but offer long-term savings through increased efficiency and reduced maintenance needs . Durability is crucial, as the furniture must withstand repeated thermal cycles without significant degradation. Additionally, the choice of material can impact the accuracy of the firing process, as materials with higher thermal conductivity can provide more uniform heat distribution. Replacement and maintenance costs should also be considered, as some materials may require more frequent replacement due to wear and tear.
