sintering temp is in general nothin but the temp at which the grains of solid formed from powder start connecting through its boundries and merge so forms a larger grain. its generally between 2/3rd of melting temp of that material.

Relation between melting temperature and sintering temperature?
The idea of sintering is heating a powder until it is hot enough to stick to itself, then reshaping it and letting it set. The temperature used is always lower than the melting point of the material.
What is the difference between sintering and annealing?
Annealing and Sintering are the same processes.
What is sintering point of compound NaCl?
The melting (not sintering) point of sodium chloride is 801 0C.
When was Ironton Sintering Plant Complex created?
Ironton Sintering Plant Complex was created in 1924.
What is the difference between calcination temperature and sintering temp?
calcination - basically is a single step heating process where it determines either further heat treatment (sintering) is necessary or not. For example, let say BaTiO3. the reaction between BaO and TiO3 definitely will produced BaTiO3 without having intermediate phase. Although, secondary phase might presence, however, it may decrease with increasing calcination temperature. By the way, if the intermediate phase is a must for next reaction, then calcination has to be followed by sintering process (to provoke further reaction). Sintering is well-known in whiteware as to produce solid body by particle diffusion. However, regards to the calcination process which is formation of intermediate reaction need to be undergo sintering process to ensure all those reaction occur in calcination process are completely reacted to form another a very stable phase.
What is binder burnout and sintering?
In ceramic processing, polymers are often added to ceramic particles to allow for higher densities and sufficient green strength. The green body, or pre-fired ceramic, must have sufficient strength to hold its shape after being pressed. Binder burnout is a processing step performed before sintering, where the green body is heated until the polymer binder is burned out of the ceramic. Sintering is the process by which ceramics are densified. Sintering is done because ceramics have very high melting temperatures and reactive melts. In sintering, the green ceramic is heated to a high temperature, below the melting point of the ceramic, where high rates of diffusion are possible. The ceramic particles are joined into a solid monolith through diffusional movement of atoms.
Is sintering mandatory for powder metallurgy Why?
Sintering welds the metal powder grains together without melting them completely. This produces a solid but porous piece of metal.
Where can one obtain more information about Laser Sintering?
There are several websites where an individual can obtain more information about laser sintering. Examples would include Wikipedia and the Free Dictionary.
What is the method sintering used for?
Sintering is a method for creating objects from powders. It is based on atomic diffusion. Powder is heated to near it's melting point in a mold and then allowed to reform.
What has the author Marc R Freedman written?
Marc R. Freedman has written: 'Improved consolidation of silicon carbide' -- subject(s): Density measurement, Dies, Pressing (Forming), Silicon carbide, Silicon carbides, Sintering 'A sintering model for SiCw/SiN composites' -- subject(s): Sintering, Silicon nitride
What is meant by selective laser sintering?
Selective laser sintering is the process of using an additive in a manufacturing technique that uses an ultra high powered laser and is used for prototype models and functional components.
What is the advantage in making an alloy by mixing the elements as powders then heating them?
We can avoid high temperatures and save energy; but generally sintering occur at some temperature - of course under the melting point of the alloying elements.
