Sintering Setters
Summary
C12 Sintering Setters include porous magnesia and alumina plates, both of which are available as setter and cover plate variants. In addition to creating a level firing surface for technical ceramic parts, these porous plates are designed to vent gases that are generated during the sintering process to avoid damaging fired parts.
Description - Porous Magnesia Plates
C12 Porous Magnesia Plates are ideal for sintering solid oxide fuel cells (SOFC), electrolyte substrates, orthopedic or dental ceramics, and for debinding and sintering metal injection molded (MIM) components. In addition to keeping parts flat and distortion-free, C12 Porous Magnesia Plates provide a smooth, non-reactive porous surface that prevents sticking and cracking. C12 Porous Magnesia Plates are highly planar, and have a porosity of about 38% which permits gasses that evolve during sintering to pass easily through the plate. Composed of high purity (99.4%) magnesium oxide, C12 Porous Magnesia Plates remain inert and non-reactive at high temperatures where other materials fail. Due to the fact that MgO has a melting temperature which is significantly higher than any other common oxide ceramic (>3100 K), C12 Porous Magnesia Plates resist warping better than standard alumina plates, and typically have a longer service life. C12 Porous Magnesia Plates can be used in conjunction with C12 Separator Powder Sheets (SPS) to help prevent sticking and damaging delicate green parts.

C12 Porous Magnesia Plates are ideal for preventing sticking, cracking and “setter drag” problems.
Advantages
♦ Prevents sticking, cracking and “setter drag” problems.♦ Resists warping, better mechanical strength than standard porous alumina plates.
♦ Higher service temperatures (over 1600 C), and longer service life.♦ Provides non-reactive, high temperature support where other materials fail.♦ Highly planar, dust-free, particle-free surface.♦ Remains electrically insulating at high temperatures.♦ Plates can be easily cut to size with laser or waterjet.♦ Better thermal shock resistance than alumina.
♦ C12 Porous Magnesia Plates are available in a range of standard sizes and thickness. Custom sizes and thickness are available on request.
Description - Porous Alumina Plates
C12 Porous Alumina Cover Plates make ideal lightweight cover or setter plates for debinding and sintering green ceramic tapes, Low Temperature Co-fired Ceramics (LTCC), electronic substrates with precious metal thickfilms, Metal Injection Molded (MIM) components, dental ceramics, sensor membranes, and 3D printed components. In addition to keeping parts flat and distortion-free, C12 Porous Alumina Plates provide a smooth, non-stick porous surface that prevents cracking and “setter drag”. C12 Porous Alumina Plates can be supplied in almost any custom size or shape. C12 Porous Alumina Cover Plates are available with a gross density of about 2.65 g/cm3 and thickness ranging from 1mm to 2mm.
C12 Porous Alumina Cover Plates are highly planar, and have a porosity of about 38% which permits gasses that evolve during sintering to pass easily through the plate, while keeping parts flat and distortion-free. Composed of high purity (99.5%) aluminum oxide, C12 Porous Alumina Cover Plates will not stain contact surfaces. C12 Porous Alumina Cover Plates can be used in conjunction with C12 Separator Powder (SPS) Sheets to help prevent sticking and damaging ceramics with precious metal thick films. Other custom porous cover plate materials, including magnesium oxide (MgO) and zirconia, are available upon request.
