DEEN COMPANY MATERIAL TECHNOLOGIES PRODUCTS & SOLUTIONS SERVICE REASONS TO USE FUSED QUARTZ HOMEMATERIALABOUT FUSED QUARTZ Properties of Fused Quartz Fused quartz is an extraordinary material for numerous industrial applications. The single-component glass consists solely of silica (SiO2). Through its unique combination of thermal, mechanical and optical properties, fused quartz is one of the most important materials for industry and research. For the Semiconductor an Solar industries, fused quartz is used in high temperature processes because of its high softening point, low thermal expansion and excellent thermal shock resistance. It can withstand temperatures up to 1300°C and can be rapidly heated and cooled with virtually no risk of breakage. Because of its high purity, parts and systems made of fused quartz are ideal suited for industry equipment. For the Lighting industry, fused quartz is an indispensable material due to the high optical transmission from ultraviolet through the infrared light. For the Chemical industry and for laboratory equipmentation, fused quartz is used because of its resistance to acids, bases and water. With the exception of hydrofluoric acid, phosphoric acid, and alkaline compounds its properties are unaffected. For the Electronics industry, fused quartz is characterized by high dielectric strength, low electrical conductivity and superior microwave transmission even at high temperatures. The Properties in Detail Transmission Mechanical / Electrical Properties Chemical / Thermal Properties Other Properties Handling - Cleaning - Storage of Fused Quartz Fused quartz requires care in handling and use to achieve good performance. Cleanliness will help reduce devitrification and maximize the life of this material. Handle fused quartz with care and only with clean cotton gloves to avoid contamination . Wrap and store quartz in a clean, dry environment Cleaning recommendation: 1. Cleaning with non-alkali cleaning agent and/or isopropyl alcohol. 2. Rinse with deionized (distilled) water 3. Air dry in clean environment and clean wrapping COMPANYMATERIALTECHNOLOGIESPRODUCTS & SOLUTIONSSERVICE IMPRINTPRIVACY POLICYDISCLAIMERSITEMAP QSIL AG / Gewerbering 8 / 98693 Ilmenau / Germany QSIL GmbH Quarzschmelze Ilmenau / Gewerbering 8 / 98693 Ilmenau / Germany QSIL Nederland B.V. / H.M.
