Description and Specification ITO Coated Quartz Glass
ITO Coated Quartz Glass is a specialized material. It has the unique properties of quartz glass and the functionalities of an Indium Tin Oxide (ITO) coating. Quartz glass is composed of highly pure silica (SiO₂ ≥ 99.9%) extracted from sources like quartzites and rock crystals. It is known for its exceptional resistance to water and strong acids (except hydrofluoric acid). Quartz glass has a very high melting point and low thermal expansion. These characteristics make it highly resistant to thermal shock and suitable for applications that involve rapid temperature changes. Quartz glass can transmit ultraviolet and infrared light, with the degree of transmittance influenced by the additives used during manufacturing.
When coated with a thin layer of ITO, quartz glass gains transparent conductive properties. These properties enhance its optical transparency while maintaining its basic durability. ITO Coated Quartz Glass is widely used in advanced technological applications like touchscreens, photovoltaics, and optoelectronic devices, where a combination of transparency, electrical conductivity, and thermal stability is required.
This coated glass is well-suited for applications such as micro-structuring and patterning. All transparent conductive oxide coatings have a few nanometers thick protective silicon dioxide (SiO2) layer. This layer is a protective barrier, positioning the ITO film in direct contact with a high-purity quartz layer while isolating it from the glass substrate. This design improves the functionality of LCDs by preventing the leak of alkali oxides from the soda-lime glass into the liquid crystals. As the SiO2 layer blends in well with the coating process, it greatly enhances the performance of ITO Coated Glass without raising prices. Its unique characteristic of blocking alkali ions is useful for various electronic applications.
