Where is germanium used most?
Germanium is primarily used in the production of semiconductors for electronic devices such as transistors and diodes. It is also used in infrared optics, fiber optics, and as a catalyst in polymerization reactions.
What is the mechanism of coordination polymerization?
The mechanism is poorly understood because it takes place on the surface of an insoluble particle, a difficult situation to probe experimentally. The mechanism shown below is one of several models proposed to at least partially explain the action of the Ziegler-Natta systems, but it is only an approximation of the more complex process that actually occurs.
What is the Process of linking monomers to form a polymer?
In a polymerization process, monomers are linked together by chemical bonds to form a polymer chain. This typically involves a reaction where the monomers undergo a series of steps to form polymer chains of various lengths. The process can be initiated by heat, light, or a catalyst, and the resulting polymer can have different properties depending on the monomers used and the polymerization conditions.
What is the process by which monomers link together to form polymers?
The process by which monomers link together to form polymers is called polymerization. During polymerization, monomers undergo a chemical reaction that causes them to bond together through covalent bonds, forming long chains of repeating units known as polymers. This process can be initiated by heat, light, or a catalyst.
What is the uses of yttrium?
Yttrium is used in various applications, such as producing red phosphors for color televisions and LEDs, as a catalyst in polymerization reactions, and in superconductors and ceramics. It is also used in medical imaging to improve the quality of images obtained from MRI scans.
What metal is used as the catalyst metal in the ethylene polymerization?
Traditionally Ziegler-Natta catalyst (TiCl3 or TiCl4 along with aluminium based co-catalyst) was used for olefin polymerization. But in recent years a variety of other complexes containing metals like aluminium, nickel, zirconium, ruthenium, iron, cobalt, hafnium, yttrium, titanium, vanadium, etc have also been employed as catalysts for olefin polymerization.
Which metal is used as a catalyst in the ethylene polymerization?
Transition metals such as nickel, chromium, and titanium are commonly used as catalysts in ethylene polymerization reactions. These metals help to initiate and control the polymerization process, leading to the formation of polyethylene with specific properties.
Where is germanium used most?
Germanium is primarily used in the production of semiconductors for electronic devices such as transistors and diodes. It is also used in infrared optics, fiber optics, and as a catalyst in polymerization reactions.
What is two part epoxy?
The two parts are: epoxy monomer and hardener/catalyst. Upon mixing the hardener/catalyst triggers polymerization of the epoxy monomers and the adhesive sets.
Which types of polymerization techniques are used to make polystyrene?
Atactic and syndiotactic polymerization.
Which oxidising agent used for polymerization of aniline?
Potassium dichromate, Ammonium peroxidisulphate, Hydrogen peroxide can be used for polymerization of aniline.
A catalyst is added to the fiberglass resin to do what?
A catalyst is added to fiberglass resin to initiate the chemical reaction that causes the resin to harden or cure. This process is known as polymerization, and the catalyst helps speed up the curing time of the resin, allowing it to form a strong and durable composite material.

What is polymerization versus catalyst?
In polymerisation a number of monomer (basic entity of polymer) get together to form a polymer.For example carbon tetra chloride joins other molecule of latter to form teflon. Catalyst catalyse(help in completion) polymerisation reaction.
