What is the name of carbons atom?
It depends on which oxidation state the atom is in some possibilities are carbide carbonate
A share of a corporation's share is?
what is 100 rights certificate for Union Carbide Corp. dated 3-1-86 worth
Why are multinational corporations criticized and how do multinational corporations counter the criticisms?
These companies often have considerable power and influence, and as a result are often criticised for their actions. One of the most famous of such cases was the problem faced by Nestlé in selling its baby milk in Africa. Critics pointed out that Nestlé was pushing the product on people when it was likely to cause harm to babies. According to a study in the British Medical Journal in 2003, the company was ignoring a code of conduct on marketing the productto countries in Africa. In addition, events like the Bhopal chemical explosion in 1984 have attracted much criticism. The incident took place in the Indian city of Bhopal and resulted in the death of more than 3,000 people, according to official figures. The plant belonged to the American chemical multinational Union Carbide.
Is tungsten tougher that tungsten carbide?
No. Tungsten is an element, where as tungsten carbide is an alloy, or a mixture of elements (tungsten, nickel, tantalum, niobium, titanium, and chromium). Tungsten carbide is much easier to work into styles and designs, but does not change the hardness of the metal.
What is Carbide?
"Carbide" as used in "Carbide Drills" and "Carbide Saws" is the alloy Tungsten Carbide. Chemically the material is either Tungsten Carbide (WC) or Tungsten diCarbide (WC2). Carbide is used because of its hardness.
What is tungsten hardness?
Tungsten is a very hard metal, ranking around 6.5-7.5 on the Mohs scale of hardness. It is known for its high tensile strength and resistance to abrasion and corrosion, making it a popular choice for various industrial applications where hardness is required.
What category of materials does tungsten carbide belong?
Tungsten carbide belongs to the category of ceramics or "hard materials." It is a compound made of tungsten and carbon and is known for its exceptional hardness and durability, making it widely used in applications requiring wear and abrasion resistance.
Can tungsten carbide tarnish?
No, tungsten carbide is highly resistant to tarnishing or corrosion due to its hardness and chemical inertness. This makes it a popular choice for jewelry and industrial applications that require durability and longevity.
Can a tungsten carbide ring be resized?
Tungsten carbide rings cannot be resized. Due to their extreme hardness and durability, tungsten carbide rings cannot be resized like traditional metals such as gold or silver. It is recommended to ensure the correct size before purchasing a tungsten carbide ring.
What is the solute and solvent of tungsten carbide?
In the context of tungsten carbide, the solute is tungsten carbide itself (the solid compound of tungsten and carbon) and the solvent would be the medium in which tungsten carbide is dissolved, which is typically a liquid like cobalt or nickel in the case of cemented carbide materials.
What material mould would use for tungsten carbide tips making?
mold for tungsten carbide
What two compounds are used to make tungsten carbide?
Tungsten Carbide is made from compounds of Tungsten and Carbon. At the base level, Tungsten Carbide resembles a type of fine dark powder. This powder then made into shapes by being pressed.
What is the examples of hardness?
Examples of hardness include diamond, which is the hardest natural substance, and materials like tungsten carbide and ceramics which are known for their high hardness and abrasion resistance. Hardness is a material's ability to resist deformation or scratching under applied pressure or force.
What are the differences between a tungsten carbide wedding band and a platinum wedding band?
Tungsten Carbide is a composition containing equal parts of Tungsten Metal (W) and Carbon (C). While Platinum (Pt) is a metal in and of it self. The letters in parenthesis indicate the chemical symbol on the periodic table. There are many differences physically between tungsten and platinum. Platinum is slightly brighter and has more of a silver shine, while tungsten carbide has a dark, shiny hue. On the Mohs scale of hardness, platinum has a hardness rating of about 4.5 out of 10, while tungsten carbide is a staggering 9.5 (Diamonds are a 10). Although tungsten carbide is harder to scratch, it is also brittle and can shatter if more than enough force is applied (ie falling from a high place, throwing it against the wall, smashing it while on a vice grip). Platinum and other lesser metals will simply take the scratch or dent, but won't shatter or break apart easily.
What elements make up tungsten carbide?
Tungsten and carbon
