CAS 12401-56-8 Hafnium Silicide HfSi2 for ceramic materials and
Brief introduction of Hafnium silicide HfSi2
Hafnium (atomic symbol: Hf, atomic number: 72) is a Block D, Group 4,
Period 6 element with an atomic weight of 178.49.
In its elemental form, hafnium has a lustrous silvery-gray
Hafnium does not exist as a free element in nature.
It is found in zirconium compounds such as zircon.
Hafnium is often a component of superalloys and circuits used in
semiconductor device fabrication .
Its name is derived from the Latin word Hafnia, meaning Copenhagen,
where it was discovered.
Silicon (atomic symbol: Si, atomic number: 14) is a Block P, Group 14,
Period 3 element with an atomic weight of 28.085.
Silicon makes up 25.7% of the earth's crust, by weight, and is the
second most abundant element, exceeded only by oxygen.
The metalloid is rarely found in pure crystal form and is usually
produced from the iron-silicon alloy ferrosilicon.
Silica (or silicon dioxide ), as sand, is a principal ingredient of
glass, one of the most inexpensive of materials with excellent
mechanical, optical, thermal, and electrical properties.
Ultra high purity silicon can be doped with boron, gallium,
phosphorus, or arsenic to produce silicon for use in transistors,
solar cells, rectifiers, and other solid-state devices which are
used extensively in the electronic industry .
