Fused silica plates are manufactured using a variety of methods. One of the most common methods is electric fusion. This process involves melting high-purity silica in an electric arc furnace. The molten silica is then poured into a mold and allowed to cool and solidify.
During the electric fusion process, the temperature of the furnace is carefully controlled to ensure that the silica melts evenly and completely. The resulting fused silica plates are highly uniform in thickness and have excellent optical properties.
Another common method for manufacturing fused silica plates is flame fusion. This process involves melting silica using a high-temperature flame. The molten silica is then allowed to flow onto a substrate, where it cools and solidifies.
Flame fusion is often used to produce large sheets of fused silica, which can be cut and shaped into a variety of forms. This process is also highly efficient and can produce high-quality fused silica plates at a relatively low cost.
Overall, both electric and flame fusion are effective methods for manufacturing fused silica plates. However, the specific method used will depend on the desired properties of the final product and the manufacturing requirements of the application.
