The presence of pores in a ceramic leads to a lower Young's modulus compared to dense material. For the development of porous ceramics with tailored elastic properties, an exact determination of the Young's modulus is required, especially for industr

The replica technique is one of the most established manufacturing methods of highly porous scaffolds for bone tissue engineering. Despite a multitude of possible templates, this method is limited in terms of reproducibility and periodicity. We overc

Lead-free piezoceramics are gaining interest in the field of bone tissue engineering due to their surface charges and improved bone cell adhesion. However, monolithic materials are less suitable for more complex medical conditions, as the properties

Porous functional graded ceramics (porous FGCs) offer immense potential to overcome the low mechanical strengths of homogeneously porous bioceramics used as bone grafts. The tailored manipulation of the graded pore structure including the interfaces

The Replica technique as a well-established method is limited in terms of pore shape, distribution by its natural or synthetic templates. We combined therefore Replica techniques with additive manufactured (AM) templates to produce foams with a perio

In this work, polycrystalline mullite whiskers are synthesized by fluoride-assisted method from metakaolin and several aluminum-containing compounds such as γ-Al(OH)3, AlF3·3H2O, and α-Al2O3 (corundum). The mullite formation and crystallization ar

The investigations on ceramic foams with porous, heterogeneous microstructure are based on the standards and dimensions for dense materials due to the lack of alternatives. It is known that variations in pore size, shape and porosity have a significa

Biosilicate® glass-ceramics are among the most valid alternatives to 45S5 Bioglass. They combine a similar bioactivity and bioresorbability as the 45S5 with superior mechanical strength, owing to the crystallization of a Na–Ca silicate phase. This
