GE214LD

Large Diameter quartz tubes used by the semiconductor, fiber optic and related industries, for their purity, sag resistance, low OH (hydroxyl), low alkali and excellent physical characteristics.

GE214LD is a natural quartz grade, which is also available as GE214LDA "low hydroxyl", GE224LD "low alkali" and GE244LD "low aluminum / low alkali" variants.

Properties and chemical composition of quartz GE 214 as well as other types of quartz glass, are discussed in detail in chapter Our offer/Technical glass/Types of materials/Quartz glass.  Below presents the most important of them.

Properties of different types of glasses are discussed here.
