Setter / kiln furniture
Kerafol® manufactures setter plates for high demands on geometry and material quality for your components. The setters are manufactured pressure less by tape casting process. Beside other ceramic production operations like die casting, dry pressing or extrusion our tape casted products Kerafol® setters have no inhomogeneous particle distribution inside the setter matrix. The pore distribution and the pore size is homogenous over the complete product matrix. The setter can be used for sintering and debinding MIM, CIM, PZT or SOFC products. The porous sintered setters are characterized by the following properties:
Aluminiumoxid 99.5 % porous
Porous, alumina content 99.5%
Due to the low heat capacity, the demand of energy for the kiln is lower, compared to conventional setter and kiln furniture. The demand of time and energy for heating up and cooling down the kiln furniture is significantly reduced by using Kerafol setter plates.
Our customers use these setters for sintering Low Temperature Co-fired Ceramics (LTCC), Solid Oxide Fuell Cells, dental ceramics and for debinding and sintering metal injection moulded (MIM) components. The high planarity of Keralpor 99 leads to accurate sinter results. Due to the high porosity of the alumina matrix the gases can diffuse through the setter during the debinding and sintering process easily.
The parts do not adhere to the setter during the debinding process. Keralpor 99 can be used best as a setter plate on your silicon carbite, mullite, korundum, molybdenum or grafite kiln-furniture.
92% alumina + 8% zirconia
The Keralpor S is a setter, which can be used for sintering various of metal injection moulding (MIM) - products and materials. The advantage of this porous zirconia thoughened alumina is its good thermal shock resistance and high mechanical strength. Through the 38% porous structure, adhesion of the sintered part will be prevented.
Due to the porous structure of the setter, adherences of the overlying green ware can be avoided. Customers use Keralpor S especially for debinding and sintering MIM products and when the cooling process in the kiln is fast.
All sizes are available with a thickness of 1.6 mm!
Please ask for you tailormade dimensions and we will create your Keralpor S quickly.
Tape for one-way use with 99.7% alumina
Our RT is a tape for one-time use. It consists of almost 87% of special alumina powder, which is embeded in a special organic carrier matrix. The high fl exibility allows, for example, also the lining of 3D setters in the sintering and casting technology. The organic components of the tape are free of phthalates and burns free of residue at temperatures of about 500°C and oxidizing kiln atmosphere. The remaining alumina powder prevents adhesion of the products to the setter and allows an optimum slipping and shrinkage of the sintered product during the firing process.
