Customized offer

Saint-Gobain Quartz is offering a large portfolio of products with various dimension but is also happy to design specific geometries or shapes, including odd ratios between diameter and length even above 1:3. In addition, Quartz raw material purity is a parameter that can be adjusted in order to find the best compromise between cost and quality in the application. Lastly specific coatings can be put on the crucible surface thanks to a proprietary process in order to make its behavior more suitable to our customer’s needs.
