Historically, liquid phase sintering was used to process ceramic materials like clay bricks, earthenware, and porcelain.Modern liquid phase sintering was first applied in the 1930s to materials like cemented carbides (e.g. WC-Co) for cutting tools, porous brass (Cu-Sn) for oil-less bearings, and tungsten-heavy alloys (W-Ni-Cu), but now finds applications ranging from superalloys to dental ...
Liquid phase sintering is the process of adding an additive to the powder which will melt before the matrix phase. The process of liquid phase sintering has three stages: rearrangement – As the liquid melts capillary action will pull the liquid into pores and also cause grains to rearrange into a more favorable packing arrangement.
Fritted glass is finely porous glass through which gas or liquid may pass, made by sintering together glass particles into a solid but porous body. [1] This porous glass body can also be called a frit. Applications in laboratory glassware include use in fritted glass filter items, scrubbers, or spargers.
Molecular crystals, liquid crystals, colloids, micelles, emulsions, phase-separated polymers, thin films and self-assembled monolayers all represent examples of the types of highly ordered structures which are obtained using these techniques. The distinguishing feature of these methods is self-organization in the absence of any external forces.
Sintering: By sintering, the pre-formed green bodies are compressed and hardened. In order to do this the green body is heated to a temperature below the melting temperature. The sintering process consists of three phases: First, the volume and the porosity is reduced and secondly, the open porosity is reduced.
