High Purity Metals

Home > Semiconductor Materials > High Purity Metals

Antimony(Sb)

High purity applications for antimony include III - V compound semiconductors used in the production of diodes, infrared detectors and Hall-effect devices. Other uses are as dopants, for thin film deposition and ultra-pure standard preparation.

Forms available: Ingots / Pieces / Shots / Powder

Purity: 4N5

Arsenic(As)

We are also able to offer some 7N arsenic MBE quality, 145g ingots 18-22mm dia x 88mm, individually packed under neutral atmosphere. Certificate of Compliance & GDMS analysis available.

Bismuth (Bi)

Known since ancient times, bismuth is a fragile pinkish-white metal that was long confused with lead, tin and zinc. In 1753, French chemist Claude Francois Geoffroy dispelled the confusion when he first published on this metal. Most bismuth comes from by-products of the extraction of lead, copper, tin, silver and gold.

We sell bismuth to manufacturers of thermoelectric devices, who use alloys of bismuth telluride and bismuth antimonide to produce water fountains and portable coolers and, more recently, by the automotive industry to cool car seats.

Purity: 4N 4N5 5N

Cadmium (Cd)

Cadmium is a shiny, bright white metal with bluish reflections that was discovered in 1817 by German pharmacist Friedrich Stromeyer. Present in most zinc ores, cadmium is obtained as a by-product of zinc refining. A significant percentage of world cadmium production comes from recycled materials.

Cadmium is used in solar applications (CdTe, CdS) and in CdZnTe for nuclear radiation detectors (X-ray, gamma ray).

Purity: 5N 6N 6N+ 7N

Indium(In)

Indium is produced mainly from residues generated during zinc ore processing but is also found in iron, lead and copper ores. Canada is a leading producer of indium. The Teck Cominco refinery in Trail BC, located minutes away from Firebird Technologies, is one of the world's largest sources of 4N indium, ensuring us a stable supply. Available in shot and ingot.

Selenium (Se)

Selenium is a non-metallic chemical element discovered in 1817 by Swedish chemist Jons Jacob Berzelius while preparing sulphuric acid. Typically, it is extracted from copper residues along with tellurium and other precious metals. In trace amounts, this element is essential to cell life.

We sell selenium to manufacturers of zinc selenide (ZnSe). This compound is transparent under infrared light and is used to manufacture lenses for carbon dioxide (CO2) lasers. Selenium is also used in CIGS and CIS for the photovoltaic solar industry and for thermoelectric devices.

Tellurium (Te)

Tellurium was discovered in 1782 by Austrian chemist Franz Joseph Muller von Reichenstein. Despite its metallic appearance, it is a semi-metal or metalloid, extracted primarily from residues produced by copper and lead refining.

High-purity tellurium is an essential component in the manufacturing of cadmium telluride (CdTe) solar cells and thermoelectric devices. Tellurium is also used to make rewritable optical discs (CDs, DVDs and Blu ray), and for the new generation of random access memory (RAM) known as PRAM.

Purity: 4N 4N5 5N 6N 6N+ 7N 7N+

Tin(Sn)

High purity applications for tin include ultra-pure standards preparation, feed for single crystal growth and high purity solder in semi-conductor applications. This includes aerospace, defense and medical related industries. Available as shot and bar.

Zinc (Zn)

Zinc is an abundant light-blue metal that has been used since ancient times. However, it was not until 1746 that German chemist Andreas Sigismund Marggraf succeeded in isolating pure zinc. Zinc production from ore makes use of two distinct technologies: pyrometallurgy and hydrometallurgy.

High-purity zinc is used to synthesize certain semiconductors such as CdZnTe, a preferred material for infrared substrates and nuclear radiation detectors.

Cadmium Sulfide

Prized in the 1800s for its yellow colour, cadmium sulfide was initially used as a pigment in paints and later in plastics. Today, the semiconducting properties of high purity CdS make it a candidate for other applications. In a thin layer, CdS is a critical component of CdTe and CIGS solar cells.

Purity: 5N

Cadmium Telluride

Our supplier has the distinction of being the leading supplier of cadmium telluride (CdTe) and cadmium sulfide (CdS) to the solar cell (photovoltaic) industry. Cadmium telluride is a semiconductor that enables the efficient conversion of solar energy into electricity. Typically, 5N purity cadmium telluride is required for this type of application. CdTe is also used to manufacture nuclear radiation detectors (X ray and gamma ray) for medical use.

Purity: 5N 6N 6N5 7N 7N+

Zinc Telluride

Zinc telluride is a translucent, reddish-orange semiconductor compound that is used to manufacture LEDs, as well as in optoelectronic applications. It is also used in some cadmium telluride (CdTe) based solar cells, and terahertz radiation detectors.

Forms available: Ingots / Pieces / Shots / Powder

Purity: 5N 6N 6N+ 7N 7N+

Cadmium Zinc Telluride

Cadmium zinc telluride is used to manufacture radiation detectors (X ray and gamma ray) that do not require cooling, and that produce excellent resolution by directly converting radiation into an electric signal. Raw materials (tellurium, cadmium, zinc, telluride) of very high purity are required to manufacture this type of detector.
