Q & A

The thermal expansion coefficient of refractory materials varies depending on the specific type of refractory material. However, in general, refractory materials have low thermal expansion coefficients, typically ranging from 1 x 10^-6 to 5 x 10^-6 per °C.

Refractory coatings offer several advantages for oxidation resistance. Firstly, they provide a protective barrier that can prevent the oxidation of underlying materials, thereby extending their lifespan. Secondly, these coatings can withstand high temperatures, making them suitable for use in applications where oxidation is a concern. Additionally, refractory coatings exhibit excellent adhesion to various substrates, ensuring long-lasting protection. Lastly, these coatings are often chemically inert, meaning they do not react with the surrounding environment, further enhancing their resistance against oxidation.

Yes, refractory materials can be used in thermal barrier coatings. Refractory materials are known for their high melting points and thermal resistance, making them suitable for protecting against extreme temperatures. When applied as a coating, refractory materials can enhance the thermal insulation properties of the barrier, allowing it to withstand and protect against heat transfer more effectively.
