what is bulk metallic glass?

(m)\n\nAn amorphous metal is a metallic material with a disordered atomic-scale structure. In contrast to most metals, which are crystalline and therefore have a highly ordered arrangement of atoms, amorphous alloys are non-crystalline. Materials in which such a disordered structure is produced directly from the liquid state during cooling are called "glasses", and so amorphous metals are commonly referred to as "metallic glasses" or "glassy metals". However, there are several other ways in which amorphous metals can be produced, including physical vapor deposition, solid-state reaction, ion irradiation, and mechanical alloying. Amorphous metals produced by these techniques are, strictly speaking, not glasses, but materials scientists commonly consider amorphous alloys to be a single class of materials, regardless of how they are prepared.

The bulk is cellulose or cellulose derivatives or processed cellulose, aka, paper.

Refractory metals are a class of metals extraordinarily resistant to heat, wear and corrosion. These properties make them useful in many applications. Household incandescent bulbs contain refractory metals in their tungsten filaments, and nearly all manufactured goods, particularly those containing metal or electronics, contain or were produced using refractory metals. Refractory metals include, Tungsten, W, Tantalum, Ta, Molybdenum, Mo, Niobium, Nb, and Zirconium, Zr.

While Glass is technically not a metal being composed of silica compounds of various types, the quickest cooling true metal is mercury...yes mercury is a metal...titanium is next followed by bauxite the main ingredient in aluminum.

All all of them bend, stretch and break. But glass has a very low capacity for bending, it is microscopical. Metal stretches, but it has a very low capacity and so on.

A crystal shape is the arrangement of the molecules in a compound...carbon fiber is a crystalline structure since it is arranged in a pattern when observed under a microscope. Glass, however isn't a crystalline structure, and will be disorganized. Also, a quick fact is that glass will always be in motion due to it's non-crystalline structure. The bottom of a pane of glass will be thicker than the top after many years :) A high melting point means that it will take more heat to induce a state change... Metal is frozen at room temperature and has a high melting point, as opposed to water, which has a melting point around 33 degrees farenheit.

Metals, Nonmetals, & Metalloids\n\nMost periodic tables contain a stairstep line which allows you to identify which elements are metals, nonmetals, and metalloids. Following are descriptions of each of the three types of materials.\n\nMetals\n\nMost elements are metals. 88 elements to the left of the stairstep line are metals or metal like elements.\n\nPhysical Properties of Metals:\n\nLuster (shininess) \nGood conductors of heat and electricity \nHigh density (heavy for their size) \nHigh melting point \nDuctile (most metals can be drawn out into thin wires) \nMalleable (most metals can be hammered into thin sheets) \nChemical Properties of Metals:\n\nEasily lose electrons \nCorrode easily. Corrosion is a gradual wearing away. (Example: silver tarnishing and iron rusting) \nNonmetals\n\nNonmetals are found to the right of the stairstep line. Their characteristics are opposite those of metals.\n\nPhysical Properties of Nonmetals:\n\nNo luster (dull appearance) \nPoor conductor of heat and electricity \nBrittle (breaks easily) \nNot ductile \nNot malleable \nLow density \nLow melting point \nChemical Properties of Nonmetals:\n\nTend to gain electrons \nSince metals tend to lose electrons and nonmetals tend to gain electrons, metals and nonmetals like to form compounds with each other. These compounds are called ionic compounds. When two or more nonmetals bond with each other, they form a covalent compound.\n\nMetalloids\n\nElements on both sides of the zigzag line have properties of both metals and nonmetals. These elements are called metalloids.\n\nPhysical Properties of Metalloids:\n\nSolids \nCan be shiny or dull \nDuctile \nMalleable \nConduct heat and electricity better than nonmetals but not as well as metals

I think it's these metals chrome, cobalt, titanium, or ceramic materials can be used.  I think they have recalled ceramic because they were cracking though.

The answer is glass... glass is an amorphus solid, meaning that it has solid characteristics, but is technically "flowing"

Fiberglass or fibreglass is material made from extremely fine fibers of glass. It is widely used in the manufacture of insulation and textiles. It is also used as a reinforcing agent for many plastic products; the resulting composite material, properly known as glass-reinforced plastic (GRP) or glass-fiber reinforced epoxy (GRE), is called "fiberglass" in popular usage.

Yes, glass is technically a supercooled liquid. It has an amorphous structure and it actually flows under gravity. Windows in old buildings are thicker at the base than at tha top due to this property.

The glass can be considered as been vitreo. The great difference between glasses and the other materials is high viscosity above of the fusing point. It is characterized by a physical solid behavior with liquid structure, that is, it is a intermediario point between I eliminate it and the solido one and does not possess symmetry. Its moleculas does not hold as I eliminate, that relatively they are joined and nor as solidos that extremely they are joined.  \nI wait that voce has understood.  \nIt forgives for possiveis errors of gramatica, text orininalmente in Portuguese.    \n\nKlarc - student of Engineering of Producão - Brazil

This is pretty much a question of the definition you are using.\n\nIn a strict definition, conventional solids have a crystalline structure. Under this definition, glass is a supercooled, highly viscous liquid rather than a conventional (crystalline) solid. \n\nIn many ways, glass acts like a solid. Using that behaviour as a criterion, glass is a solid.

It is a very pure conductive metal. More pure than gold. Indeed.

Metals are shiny and are good conductors of heat and electric current. They are malleable and ductile.\nNon-metals are dull, and are poor conductors of heat and electric current. They're brittle and unmalleable.

METALS ARE MALLEABLE AND DUCTILE INDEED THEY ARE VERY STRONG SOME METALS LIKE ALUMINIUM HAS A LOW DENSITY SO IT'S USED IN BUILDING AIRCRAFTS,IOW DENSITY COOKING UTENSILS ETC.. ALLOYS EG:STEEL IS ALSO USED IN UTENSILS ....COINS ARE ALLOYS OF NICKEL AND COPPER.....METALS USUALLY HAVE A HIGH MELTING POINT.......

A ductile substance is easily pulled or stretched into a thin wire without breaking.\n\n"...gold is the most ductile metal and one gram of it can be drawn into a wire 2,300 meters long."\n\n"The order of ductility of some familiar metals is gold > silver > platinum > iron > copper > palladium > aluminum > zinc > tin > lead"
