Lithoz’ Ceramic Materials

Lithoz offers its customers various materials for the additive manufacturing of high-performance ceramics. Each raw material is perfectly adjusted to fit Lithoz’ complete system and enables the production of high-quality parts.

 

Lithoz’ ceramic materials enable the production of parts which exhibit equal or similar material properties to conventionally manufactured parts. Especially considering density and stability, additively manufactured components are in accordance with the high requirements of the ceramic industry and ceramic research.

"Individual customer support and customer advice is very important to us. Lithoz supports its customers with choosing the right materials."
ALUMINUM OXIDE

Aluminum oxide‘s distinguishing features are its high degree of hardness, its corrosive stability and its temperature stability. Parts made of alumina are electrically insulated and dielectrically strong.

With the LithaLox HP 500, Lithoz provides a highly pure aluminum oxide with outstanding material properties. Its high density (>99.4%T.D.), high 4-point bending strength (430MPa) and very smooth surface (Ra = 0.4 μm) are all noteworthy properties.

LithaLox 350 D is an advanced development for the realization of highly-complex components with canals and boreholes of small diameter.

ZIRCONIUM OXIDE

3 mol % yttria stabilized zirconia distinguishes itself with its especially high stability towards thermal, chemical and mechanical influences. Its high density and impact resistance further underline this material‘s many advantages.

LithaCon 3Y 610 Purple features a 4-point bending strength of 700MPa and a density of 6.04 g/cm3 (99.8 % T.D.). The surface roughness (Ra) amounts to 0.6μm.

Various colors are available upon request!

SILICON NITRIDE

Due to its exceptional combination of properties, silicon nitride is put to use where the highest mechanical strain or severe thermal cycling take place. Being highly stable while simultaneously low in density, silicon nitride is especially interesting for lightweight construction.

LithaNit 720 is a silicon nitride with sinter additives (Al2O3, Y2O3) which can be employed for industry as well as aerospace applications. LithaNit 720 reaches a density of 3.25 g/cm3, a biaxial strength of 760 MPa and a density (HV10) of 1500.

BONE-REPLACEMENT MATERIAL TRICALCIUM PHOSPHATE

Tricalcium phosphate (TCP) is especially suited as bone-replacement material because it is resorbed by the body. It facilitates the production of patient-specific implants with defined pore structures and geometries and is ideal for realizing bionic designs, fine canals and defined cellular pore structures.

LithaBone 200 is TCP-based and has coordinated mechanical properties and microporosity dependent on the applied sintering conditions. The material can be used as bioresorbable bone replacement material. To induce bone growth, printed parts can be modified using growth factors. Relative density can be varied between 75 % and 90 % in accordance to strength levels of 20 to 33 MPa.

LithaBone 300 D is an advanced development based on ISO 13485-certified TCP powders.

SILICA-BASED MATERIALS FOR CASTING CORES

Silica-based materials with various additives have already established themselves as a staple in the production of casting cores due to their high temperature stability and leachability.

LithaCore 450 is a silica-based casting core material with alumina and zircon for the casting of steel and nickel-based super alloys. Its temperature stability and leachability in combination with the creative freedom of 3D-printing make it perfect for realizing virtually any design with excellent surface properties.
