refractory ceramic formed shapes
Ceramic fiber vacuum-formed shapes come in various configurations. These shapes are fabricated from alumina-silica fibers and are suitable for applications with temperatures as high as 1650°C (3000°F). To tailor ceramic fiber special shapes to specific applications, material compositions can be adjusted with different fillers and chemicals, fine-tuning properties such as strength, density, and resistance to molten metals to create unique characteristics.
