Creativity & performance in Technical Ceramics Kiln Furniture Leveraging on its expertise in designing, composing, shaping and firing ceramics, Imerys develops kiln furniture solutions for a wide range of technical ceramics manufacturings. These kiln furniture solutions are designed to fit the needs of several industries: • car • electrical/electronics • medical • wear parts Our wide range of high quality body compositions (silicon carbide, cordierite, mullite, alumina and zirconia) is a solid cornerstone to the custom-building of the required kiln furniture properties. Each solution is tailored to your needs thanks to our state-of-the-art design office.
VALUE-ADDED PRODUCTS
Imerys kiln furniture offers a large range of solutions for box-saggars :
• traditional with high performances
• combinaison of lid and ring – called “combo” - to increase flexibility and life time
• with specified “insert” to maintain pieces in right position during firing and keep the fired dimensions or avoid
bending
• stackable setters with tailored ribs for product positioning

We have a wide range of standard dimensions of kiln furniture, and we produce all dimensions on request. We
can also provide specific formulations as cordierite/spinel of kiln furniture depending on your needs. For all
specific inquiries, we are used to work with Non Disclosure Agreements.
Imerys kiln furniture offers a large range of solutions for batts and beams/props to build your own firing
structure. We are extremely sensitive to provide you :
• low and very low thermal mass
• very precise and stable geometric dimensions
• long life-time
• high resistance to loading

TAILORED SERVICES
Multi Layers Ceramic Capacitors (MLCC) fired at 1280°C
Problem
Avoid bending of the current “spaghetti”-rack systems (mullite) with quite
complicated manipulation.
Solution
Ultra-light RSiC-“Butterfly” rack system (Al2O3 engobed)
• assures stable flatness over service life with connector elements
(Aptamull 84)
• allows easy handling of stackable system
• MLCC components placed onto Al2O3 or ZrO2 setters
Diesel particle filters (DPF) honeycombs firing at 1450°C
Problem
Avoid DPF to loose geometric precision.
Solution
Combination of NSiC-batt with Aptamull 84 feet (LPIM):
• NSiC batts warrants flatness
• attached feet allows reduced costs
Spark-plugs fired at 1650°C
Problem
Avoid spark-plugs to bend or loose geometric precision during firing.
Solution
Use of mullite insert made with Aptamul 84 (LPIM):
• very precise hole dimensions to maintain vertical the spark-plugs
during firing
• fitted insert dimensions for existing box-saggars
• perfect for automatic handling related to loading and unloading of the
spark-plugs
