ABOUT US

SOUTHEAST QUARTZ Products has been developing, producing and selling quartz glass tubes since the beginning of the 2000s. Due to their optical and thermal properties, these are mainly used in the lamp industry, chemical industry, semiconductor and solar industry in a variety of processes. In a one-step process, the quartz glass tubes are manufactured directly and without further intermediate steps. State-of-the-art melting furnaces allow outside diameters from 7mm to 310mm, flexible wall thicknesses and lengths, and short response times for material changes. The preparation and doping of the high-purity quartz sand enables a broad portfolio of different quartz glass qualities.

In addition to quartz glass tubes, we also produces quartz glass rods in various high-purity material qualities and properties.
Our quartz glass rods are available with outer diameters from 10 mm to 50 mm and a max. length of approx. 3,000 mm, available in five material specifications.
Upon customer request, we also take over the finishing or further processing of rods.
Using our state-of-the-art vacuum annealing process, the OH content can be adjusted to <5ppm for improved response and thermal stability.

In addition to various round materials, such as quartz glass tubes and quartz glass rods, our company also has quartz glass plates in its product range. Thanks to its outstanding chemical resistance, good optical properties and extremely high temperature resistance, plate material is particularly suitable for applications where thermal processes must be performed and monitored.

Our quartz glass plates are therefore used as sight glasses in high-temperature furnaces. Due to their high UV transmittance, the quartz glass plates are also used in UV systems in which components have to be protected against dust or gases or must be cooled in a defined manner.
In optical applications, mostly synthetically produced quartz glass, so-called fused silica, is used. The plates are used, among other things, as object carriers or microscopy glasses and in laser optics.

Quartz glass plates can be tailored and dimensioned according to customer specifications with the CNC laser machine installed in the production facility in Malta. Upon request, the quartz glass plates are ground and mechanically polished by us. In doing so, we pay the utmost attention to a professional processing and a perfect starting material with the best optical properties. Our quartz glass is therefore checked after each process step.
