What is the material used to make inside of a baking oven resistant high temperatures?

The material commonly used to make the inside of a baking oven resistant to high temperatures is ceramic. Ceramics have excellent thermal properties, which allow them to withstand the extreme heat generated during baking without melting or deforming. They are also resistant to thermal shock, meaning they can endure sudden temperature changes without cracking or breaking. Additionally, ceramics are non-toxic, making them safe for use in food preparation.

Specific types of ceramic materials used in baking ovens include:

1. Refractory Ceramics: These ceramics are specifically designed to withstand extremely high temperatures. They are made from materials such as alumina, zirconia, and silicon carbide. Refractory ceramics are used in the construction of the oven's walls, floor, and ceiling, as well as the baking stones or racks.

2. Porcelain Enamel: Porcelain enamel is a type of ceramic coating applied to metal surfaces. It is made by fusing powdered glass to the metal at a high temperature. Porcelain enamel is commonly used on the interior surfaces of ovens to provide a smooth, easy-to-clean surface.

3. Ceramic Fiber Insulation: Ceramic fiber insulation is a lightweight, porous material made from spun ceramic fibers. It is used as insulation to reduce heat loss and maintain the desired temperature inside the oven.

The combination of these ceramic materials ensures that the inside of a baking oven can withstand high temperatures, resist thermal shock, and provide a durable, safe surface for baking food.
