Gold-plated quartz glass is a composite material that combines the excellent physical and chemical properties of quartz glass with the high conductivity and high reflectivity of metal coatings. Its production and processing process is relatively complicated, and requires multiple steps such as the preparation of quartz glass, surface treatment, and deposition of the gold-plated layer. Among them, the deposition of the gold-plated layer is one of the key links, and is usually carried out by electroplating, chemical plating or vacuum plating. During the production process, various process parameters need to be strictly controlled to ensure the quality and performance of gold-plated quartz glass. Gold-plated quartz glass has a wide range of applications in many fields, including but not limited to optics, electronics, communications, medical treatment, and scientific research.
