Laurel Kiln Furniture Saggars and crucibles belong to the container-type kiln furniture, and they play a crucial role in industrial production, especially in the fields related to high-temperature firing. In terms of appearance and structure, they both have specific container shapes to meet the needs of loading different items.

Product Details

Refractory kiln furniture is a critical component in high-temperature industries. Common materials include silicon carbide (SiC), alumina, mullite, and cordierite, each selected for properties like heat resistance, corrosion resistance, low thermal expansion, or lightweight design. Key types include kiln posts (vertical support), shelves (horizontal load-bearing), saggars (contamination isolation), pusher plates (product transport), and setter plates (direct workpiece holding). These components are widely used in sintering ceramics, glass, and electronics, protecting products from extreme heat while enhancing energy efficiency through optimized kiln design, ensuring both process reliability and product quality.






Sagger crucibles, as a type of kiln furniture, are extremely crucial apparatuses in high-temperature firing processes. They are usually meticulously fabricated from materials with high temperature resistance, excellent thermal shock resistance, and good chemical stability, such as silicon carbide (SiC), alumina, mullite, and cordierite, laying a solid foundation for their outstanding performance. The sagger crucible features a regular box-like or pot-like appearance and has a spacious and relatively enclosed interior space, which can effectively isolate the fired items from external impurities, creating a “clean” high-temperature growth environment for the green bodies. During the firing process, whether it's delicate ceramic handicrafts, electronic ceramics with extremely high purity requirements, raw materials for special glass, or the melting of high-melting-point metals, the sagger crucible can rely on its remarkable heat storage and insulation capabilities to precisely control the temperature, allowing heat to evenly envelop the items. This helps to produce finished products with superlative quality and pure components, significantly enhancing the product's yield rate and added value.

Sagger crucibles for kiln furniture find wide applications in multiple significant fields.


In the traditional ceramic industry, ranging from elegant art ceramics to daily-used tableware and bathroom ceramics, sagger crucibles provide a stable and clean firing environment for green bodies. They can effectively block dust, impurities, and other contaminants in the kiln, ensuring that the ceramic surfaces are smooth, delicate, and with uniform color. This greatly enhances the aesthetics and quality grade of ceramic products, allowing each piece of ceramic to perfectly showcase the creator's ingenuity.


In the field of electronic ceramics, where the environmental requirements are extremely high, sagger crucibles are even more indispensable. When firing high-precision electronic components such as chip capacitors and piezoelectric ceramics, they rely on their excellent heat insulation and temperature control capabilities to precisely maintain the appropriate temperature range, guaranteeing the stable electrical performance of electronic ceramics. This meets the stringent requirements of modern electronic products for miniaturization and high performance, providing crucial support for the stable operation of electronic products such as smartphones and computer chips.


In the manufacturing of special glass, facing the challenges of high-temperature melting and precise control of components, sagger crucibles perform outstandingly. Whether it's manufacturing high-strength, high-temperature-resistant special glass required for aerospace or special glass with excellent optical properties for high-end building decoration, they can fully melt the glass raw materials at high temperature while preventing impurities from mixing in. This helps special glass achieve excellent optical and mechanical properties, expanding the application boundaries of glass materials.


For the metal smelting industry, especially for the melting of some high-melting-point metals such as tungsten, sagger crucibles also play a crucial role. Their high-temperature resistance and corrosion resistance characteristics enable them to withstand the extremely high temperatures and chemical erosion during metal melting, ensuring that metals are melted and refined in a pure environment. This provides high-quality metal raw materials for the production of high-end products, such as aero-engine blades and metal materials for the electronic industry
