BizEsp's Oxford Indium brand covers our technologies and products in the area of high purity metals and their “transparent conducting oxides (TCO) -.,in particular “Indium Tin Oxide (ITO).

Oxford Indium focuses on:

1. Purification of metals such as indium to 5N purity grade.
2. Metal oxide powders with customised physical and chemical properties.
3. Conversion of metal oxide powders into ceramic sputtering targets.

Oxford Indium uses proprietary technology to manufacture ITO planar rectangular tiles (called 'targets') normally 650 mm length, 350 mm width and around 2 cm thick. These tiles are used in a process known as Physical Vapour Deposition (PVD) or sputtering to deposit very thin films (less than a few micro metres) onto special quality glass. The ITO thin films so deposited are highly transparent to light and electrically conducting. These two properties make ITO coated glass suitable for use in the manufacturing of all flat panel displays (like liquid crystal displays) and all solar cell devices. Currently, ITO has a monopoly in these applications as only ITO thin films are both commercially and technically viable.

The Oxford Indium process of building the ITO tiles comprises: raw indium ore ' refined into 99.99999% or 5N indium ingots ' conversion into indium oxide ' mixing with tin oxide ' casting and firing into tiles ' polishing/finishing and bonding tiles onto copper backing plates. The tiles are then shipped to clients in customised packaging.

Oxford Indium is now manufacturing the ITO tiles in collaboration with Huaxi Group of China (see news archives). Huaxi is a leading Chinese mining company with major reserves of indium, tin, zinc, antimony and silver. Huaxi Group and Oxford Indium intend to engage in further cooperation for the conversion of Huaxi's other metal reserves into value added products for use by the electronics manufacturing industry.
