A ceramic article and method of manufacturing. The ceramic article comprises a porous ceramic material having a microstructure comprising an interconnected network of porous spheroidal ceramic beads. The microstructure has a total open porosity defined as the sum of an open intrabead porosity of the beads and an interbead porosity defined by interstices between the beads in the interconnected network. The microstructure has a bimodal pore size distribution having an intrabead peak corresponding to the open intrabead porosity and an interbead peak corresponding to the interbead porosity. An intrabead median pore size of the intrabead porosity is less than an interbead median pore size of the interbead porosity.

The present invention provides a system, method, and apparatus for producing a dimensionally stable extruded board product for use in surface coverings. The board product may be a basalt casting powder-based product for use as a substrate for wall or other surface coverings or may be used as a core layer in a modular floor covering unit. The modular floor covering unit comprises multiple layers. The layers are a thin cut stone veneer layer, a core layer with a density similar to that of the thin cut stone veneer layer, and an optional magnetically receptive underlayment layer. Other layers or combinations of layers may also be used.

The present invention relates to a suspension comprising 50-95% by weight of the total suspension (w/w) of at least one metallic material and/or ceramic material and/or polymeric material and/or solid carbon containing material; and at least 5% by weight of the total suspension of one or more fatty acids or derivatives thereof. In addition, the invention relates to uses of such suspension in 3D printing processes.
