CAS 12401-56-8 Hafnium Silicide HfSi2 for ceramic materials and aerospace fields

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 appearance.

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 .
