High temperature boards are specialized materials designed to withstand extreme heat and provide thermal insulation or structural support in high-temperature environments. They are commonly used in industries such as aerospace, automotive, metal processing, glass manufacturing, and foundries. Here’s an overview of different types of high temperature boards:

1. Ceramic Fiber Boards: Ceramic fiber boards are made from refractory ceramic fibers bonded with inorganic binders. They offer excellent thermal insulation properties and can withstand temperatures up to 2300°F (1260°C). Ceramic fiber boards are lightweight, rigid, and resistant to thermal shock. They are used for furnace linings, kiln shelves, and heat shields in various industrial applications.

2. Calcium Silicate Boards: Calcium silicate boards are composed of calcium silicate and other inorganic materials. They can withstand temperatures up to 1200°F (650°C) and offer good thermal insulation properties. Calcium silicate boards are rigid, lightweight, and resistant to moisture, making them suitable for applications such as furnace linings, fireproof doors, and insulation panels.

3. Refractory Insulation Boards: Refractory insulation boards are made from refractory materials such as alumina, silica, or zirconia. They are designed to withstand temperatures up to 3000°F (1650°C) and offer excellent thermal insulation properties. Refractory insulation boards are used in high-temperature applications such as furnace linings, crucible supports, and thermal barriers.

4. High Temperature Insulation Boards: High temperature insulation boards are made from various materials such as ceramic fibers, vermiculite, or perlite. They can withstand temperatures up to 2000°F (1093°C) and offer good thermal insulation properties. High temperature insulation boards are lightweight, easy to handle, and resistant to thermal shock. They are used for furnace linings, oven insulation, and heat shields in industrial applications.

5. Graphite Composite Boards: Graphite composite boards are made from graphite fibers or graphite-reinforced composites. They offer high thermal conductivity and can withstand temperatures up to 5000°F (2760°C). Graphite composite boards are lightweight, strong, and resistant to thermal shock. They are used in aerospace, automotive, and semiconductor industries for applications such as thermal management, heat sinks, and insulation panels.

6. Ceramic Fiber Reinforced Boards: Ceramic fiber reinforced boards are made from ceramic fibers reinforced with ceramic or metallic meshes. They offer high strength, thermal insulation, and resistance to thermal shock. Ceramic fiber reinforced boards can withstand temperatures up to 3000°F (1650°C) and are used for furnace linings, kiln shelves, and heat shields in high-temperature applications.

Overall, high temperature boards are essential components in various industries where thermal insulation, structural support, and heat resistance are critical requirements. They play a vital role in maintaining temperature stability, protecting equipment, and ensuring safety in high-temperature environments.
