Answer #1

Metal-Matrix Composite(MMC) :

It is a composite material which have at least two constituent parts. One should be metal compulsorily other material can be different metal/ material. Here the reinforcements can be Alumina, Zirconia, SiC and cubic boron nitride etc. Aluminium is the most commonly used metal in MMC's.

Classification of MMC

  1. Particles Reinforced Composites
  2. Short fibers
  3. Continuous fibers

Properties

  • High specific strength
  • Good wear resistance
  • Higher thermal deformation resistance
  • Low fatigue resistance

Advantages

  • Good radiation resistance
  • There is no moisture absorption
  • Fire resistance
  • Higher electrical conductivity
  • Higher thermal conductivity
  • Higher temperature capability

Disadvantages

  • Technology is immature
  • Cost is high

Applications

  1. Drive shaft for light load motor vehicles
  2. Vented passenger car break disk
  3. Disc break caliper for passenger cars
  4. Longitudinal bracing beam fr planes
  5. Aluminum–graphite composites are used in power electronic modules as it has high thermal conductivity
  6. Used in premium bicycle frames

I just made it brief and point wise for better understanding. If you need more data please feel free to comment. I will reply ASAP. If you find my answer useful please give me a thumbs up. It will be very helpful for me.

Antimony (Sb, 121.8 g/mol) is a metal that is used in applications such as fire retardant materials, electronics, bullets, lead shot, and in lead-free solders. The primary source of antimony in nature is its sulfide, stibinite (Sb2S3, 339.7 g/mol). Pure antimony is obtained by heating pulverized stibnite with scrap iron (Fe, 55.85 g/mol), and drawing off the molten antimony from the bottom of the reaction vessel. Sb2S3 + 3 Fe ------> 2Sb + 3FeS (FeS = 87.91 g/mol). Suppose that...
