Tungsten carbides are generally called as carbides. Cobalt with Tungsten carbide acts as a binder. When Cobalt added with other elements like Ni / Cr / Mo / Ti are called as cemented carbides.
Sintering is a thermal treatment given to these carbides so as to eleminate the porosities and densify them. During this treatment cobalt binds the WC particles and we get high density.

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.
How can I make neodymium magnets?
Neodymium magnets are typically made through a process called sintering, where neodymium, iron, and boron powders are mixed together and then heated to high temperatures in a controlled environment. This process helps to align the atoms in the material, creating a strong magnetic field.
Is graphite a ceramic material?
No, graphite is not a ceramic material. Graphite is a form of carbon with a layered structure, while ceramics are non-metallic materials made through the process of firing, sintering, or other methods.
How long does it take to make an artificial magnet?
The time it takes to make an artificial magnet can vary depending on the method used. For example, creating a permanent magnet through processes like sintering or casting can take several hours to days. However, electromagnets can be created instantly by passing an electric current through a coil of wire.
How is uranium used in a mixture?
Uranium can be used in alloys, for example U-Zr-Er. Uranium can be used as mixed oxide, for example MOX = UO2 and PuO2. Uranium can be used also as mixture of carbides, molten salts mixture, solutions and suspensions, etc. but more rare.

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.
Why are carbides of beryllium and aluminium are called methanides?
Carbides of beryllium and aluminium are called methanides because they react with methane gas to form compounds. These carbides have the ability to react with methane in a way that is similar to other metal carbides, which is why they are classified as methanides.
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.
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.
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.
When carbon and uranium combine what do they make?
Uranium carbides as: UC, UC2, U2C3; uranium carbides are used as nuclear fuel and rarely as catalysts in chemical engineering.
What is the difference between sintering and annealing?
Sintering is a process of compacting and forming a solid mass of material using heat without reaching its melting point, while annealing is a heat treatment process that involves heating a material to a specific temperature and then slowly cooling it to relieve internal stresses and increase ductility. Sintering is used to form objects, while annealing is used to improve a material's properties.
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 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.
