Sinter Machine - an overview | ScienceDirect Topics
Apr 02, 2011 · Hence, compared to the conventional sintering process, the HPS process is capable of producing lower SiO 2 sinter of good strength due to the formation of solid diffusion bonding during sintering. Decreasing the sinter SiO 2 content is important for high pulverized coal injection (PCI) operation of blast furnaces.
Silicon nitride ceramics consolidated by oscillatory ...
In recent years, the oscillatory pressure sintering (OPS) process [ 10 ] has been developed based on the HPS process. In this process, an oscillating pressure with a certain frequency and amplitude is applied during the ceramic sintering process, to synthesize ceramic materials with higher density and strength …
The Sintering Process in Powder Metallurgy | GE Additive
Sintering is a heat treatment commonly used to increase the strength and structural integrity of a given material. Powder metallurgy processes use sintering to convert metal powders and other unique materials into end-use parts. Sintering typically takes place in a single, elongated furnace with different temperature zones.

Spark plasma sintering - Wikipedia
Spark plasma sintering (SPS), also known as field assisted sintering technique (FAST) or pulsed electric current sintering (PECS), is a sintering technique.. The main characteristic of SPS is that the pulsed or unpulsed DC or AC current directly passes through the graphite die, as well as the powder compact, in case of conductive samples. Joule heating has been found to play a dominant role in ...
Sintering - Wikipedia
Sintering or frittage is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction. Sintering happens naturally in mineral deposits or as a manufacturing process used with metals, ceramics, plastics, and other materials. The atoms in the materials diffuse across the boundaries of the particles, fusing the particles together and creating one …
Sintering | metallurgy | Britannica
Sintering, the welding together of small particles of metal by applying heat below the melting point. The process may be used in steel manufacturing—to form complex shapes, to produce alloys, or to work in metals with very high melting points. In a steel-sintering plant a bed of powdered iron ore, mixed with coke or anthracite,...
