Semi-Metals

Antimony (Sb) is a semi-metal that is bluish-white, extremely brittle, and flaky. It is a poor conductor of heat and electricity. Purities available from 99.99% to 99.999%

Antimony Tin Oxide (ATO) is a sustainable material due to its unique properties. ATO is an environmentally friendly alternative to Indium Tin Oxide (ITO) as a transparent conductor, which is widely used in touchscreens, flat-panel displays, and solar cells. ATO is made from readily available and low-cost raw materials, and its production does not generate hazardous waste or harmful byproducts. In addition, ATO is highly durable and can be recycled, making it a promising candidate for a circular economy. As a conductor with high optical transparency, ATO is an attractive option for a wide range of applications in the electronics industry. Its ability to be produced sustainably and recycled makes it an environmentally friendly choice for companies looking to reduce their Carbon footprint and contribute to a circular economy.

Antimony(III) Oxide (Sb₂O₃) (Antimony trioxide) is a white solid and is the most important commercial compound of antimony. Antimony(V) Oxide (Sb₂O₅) (Antimony pentoxide) is a yellow powdery solid that is very slightly soluble in water.

Antimony(III) Sulfide (Sb₂S₃), or Antimony Trisulfide, is the most common antimony mineral and the chief source of the metal. It is a black needle-like crystal and semiconductor with a direct band gap of 1.8–2.5 eV. Purity: 98.0% up to 99.99% Powder sized down to nanometers

Boron (B) is a semi-metal of which several allotropes exist. Boron is very hard and very resistant to heat. One main allotrope is a brown amorphous powder when pure. It is more reactive than crystalline boron as it slowly oxidizes in the air and can react violently with acid. Military Specifications: MIL-B-51092 (ORD), PA-PD-451, OS 11608 Grade I SB95 (93%-97% Boron purity) Particle Size range 0.8 micron max FSSS Grade II SB90 (90%-92% Boron purity) Particle Size range 1.0 micron max FSSS Grade III SB86 (86%-89.9% Boron purity) Particle Size range 1.2 micron max FSSS SB2000 (55%-77% Boron purity)

Boron (B) is a semi-metal that is very hard and resistant to heat, of which there are several allotropes. Crystalline boron is a black, lustrous semiconductor almost chemically inert at ordinary temperatures. This crystalline form is the second hardest of all the elements and has one of the highest melting temperatures. Purity: Crystalline Boron Powder: 99% Crystalline Boron Powder: 99.9% Crystalline Boron Powder: 99.99%

Boron Oxide, also referred to as Boric Acid, B₂O₃, is white, hard, glassy solid, also known as diboron trioxide. It is almost always amorphic. When hydrated, it reverts to boric acid. Its properties allow boric acid to be used to increase thermal resistance and mechanical strength. Purities are available from 98% (industrial grade) to 99.9995% (high purity grade)

Crystalline silicon is the crystalline form of silicon, a semi-metal and semiconductor. It is a lustrous, grayish-black and can be polycrystalline or monocrystalline silicon. Purity 98% min. Note: Lump, pressed targets, and many powder granulations are available to customer specification down to as fine as 50 nanometers

Fumed Silica, also known as pyrogenic silica, are powders that are available with either hydrophobic or hydrophilic surfaces. They are made with a flame, resulting in an extremely small particle with a three-dimensional structure with low bulk density and high surface area, making this powder useful as a thickener or reinforcing filler.

Germanium Dioxide (GeO₂), also referred to as Germanium(IV) oxide or Germanium Oxide, is the main commercial source of germanium. It is a highly insoluble but thermally stable germanium source with superior mechanical strength over other infrared clear glasses. These properties make it more suitable for rugged military applications. Purity: 99.998%

Germanium (Ge) is a silvery-white, bright, brittle semi-metal. It is a poor conductor of electricity, has a high index of refraction and dispersion, and is transparent to infrared radiation. Purity Up to 99.999%

Amorphous selenium is either a reddish powder, a gray metallic-looking solid, or a black, vitreous solid. This element resembles sulfur in its various forms and in its compounds. Selenium has many electrical properties, both photovoltaic, where light converts to electricity, and photoconductive, where electrical resistance decreases with increased illumination. It can also convert AC electricity to DC electricity. Purity: 99.5% to 99.99%

Silicon germanium (SiGe) is an alloy that forms very high-speed transistors that can attain switching speeds greater than traditional semiconductors. This enables faster, more efficient devices to be manufactured using smaller, less noisy circuits than conventional silicon conductors. SiGe alloys consume less power, and extending the battery life of hand-held devices allows greater integration of components onto chips.

Silicon (Si) is a semi-metal and one of the most useful elements to mankind. When ultrapure, it is solid; it has a blue-gray metallic sheen. Silicon is one of the most abundant elements on earth and is a semiconductor. Crystalline bulk silicon is inert but becomes more reactive at high temperatures. Purity 98%-99.995%

Tellurium (Te) is a brittle, mildly toxic, rare, silver-white metalloid that is crystalline. It has low electronegativity, is a p-type semiconductor, and shows greater conductivity in certain directions. Typical Purity: 99.5%, 99.99%, 99.9985%, 99.999%, and 99.9999+%
