Product Description:

Description
 
 Ferro Silicon is a kind of ferroalloy which is composed of ferrum and silicon. Ferro Silicon uses coke, quartz (or silica) as raw materials and is made by electric furnace. Because silicon and oxygen are easily compound into SiO2, the ferrosilicon is often used as deoxidizer in steelmaking. 
 
Application
 
1. Ferrosilicon is often used as deoxidizer in steel- making.  
 
2. Ferrosilicon also can be used as alloy elements join agent, which is widely used in low alloy steel, non-ferrous metal, bearing steel, heat-resistant steels and electrician silicon-steel.
 
3. It can be used as a reductant in ferroalloy production and chemical industry.
 
4. In iron industry it can be used as inoculant and nodulizer.

Q:what is biomedical metal?
If I remember right then polished cobalt has a blue tint not made by radioactivity but the surface reflections caused by it's crystals and how the crystals bend, reflect and absorb white light.
Q:Compare Random Metal Bands?
I'll do top 5s. Thrash: Exodus Overkill Kreator Warbringer Annihilator Black Metal: Absu Skeletonwitch (though they are Blackened Thrash..) Bathory Equilibrium (blackened folk) Enslaved Immortal Power Metal: Blind Guardian Iced Earth Persuader Symphony X Dream Evil Runnerup = Hammerfall Death Metal Allegaeon Obscura Death Dark Tranquility Revocation Runnerups: Cynic (Would be #1 but they're going away from Death Metal) Opeth, Edge of Sanity Cores: Not big on these, but I like a couple like Vanisher.
Q:what are late transition metals?
Korn is all that comes to mind, so I imagine Nu Metal is written in a very early form of latin, later updated to crappius musicus.
Q:How to get into metal music?
Old School Death Metal. It's still technical, it's still heavy as hell, it's a little brutal, and it's just great. I find that each band has something unique and different going on, unlike the other genres. It's like the other subgenres all combined, which is why I love it. And let's be honest here; Obituary, Suffocation, Immolation, Nocturnus, Death, Morbid Angel, Autopsy, Grave, Entombed, Atheist, Cynic, Cannibal Corpse, and so many others, are *all* old school, even if they're also a little something else. That has the other subgenres beat right there, I think. BQ: Progressive Death Metal - Cynic Technical Death Metal - Atheist Melodic Death Metal - At The Gates Brutal Death Metal - Immolation Blackened Death Metal - Belphegor Old School Death Metal - Death BQ2: Scream Bloody Gore, Altars Of Madness, Unquestionable Presence, Focus, The Sound Of Perseverance.

Q:Any Good new Death Metal Bands?
1.In metals,metallic bonding is observed.In metals the valence electrons are loosely held,hence they can be released.Thus the metal atoms are like positively charged spheres in a sea of electrons.These positively charged nucleus is known as a kernel.They are not linked to a fixed number of molecules as is the case with non-metals.There cannot be a specific formula as explained by the electron sea model. 2.A metal atom and non-metal atom usually have an ionic bond,but may also show covalent bonding as is the case with some compounds of Lithium. Two Non-metal atoms are linked by covalent bonds(or in some cases co-ordinate bonds like ozone).Two Noble gas atoms are held together by weak Van Der Waal's force but they don't form a bond. Two Metal atoms as told earlier show metallic bonding.
Q:What is the order of reactivity of hydrogen, metal X and metal Y?
The volume of water and metal is 23.4 mL. The volume of water is 15mL. Therefor, the volumen of the metal is 23.4 - 15 mL. Divide the volumen of the metal by the weight of the metal to get the density.
Q:metal gear solid 4 any good???
power metal is one of the few (the only??) metal sub- genres that for some reason leaves me cold... bar a very few bands... Helloween, and erm... when i was getting into metal i lived in the UK and no-one i knew listened to 'power metal'... me and my friends preferred metal that was derived from 'blues' or 'punk'. I've since moved to the continent (Spain) and i can't get away from the more melodic 'classical' influenced power metal stuff... and i'm afraid, bar the odd standout tune, i can't stand it!
Q:viking metal, pirate metal?
