Alumina has high melting point and boiling point, high hardness, insulator at room temperature and conductivity at high temperature. Alumina has been used as refractory for melting glass and steel since the 1920s. Zirconia ceramics are widely used in structural ceramics because of their high toughness, flexural strength, wear resistance, excellent thermal insulation and even their thermal expansion coefficient close to metal. In this paper, the important properties and mechanism of zirconia ceramics and its application in various fields are introduced.

From the point of view of development and growth rate, China's refractory industry has farewell to the period of rapid development, and the development mode is transiting to the stage of industrial transformation and upgrading. In the past, purely pursuing the extensive growth of production capacity has no longer adapted to the development trend of the market. At present, the refractory industry is facing a serious imbalance between supply and demand, showing a situation of oversupply. Therefore, the emergence of refractory bricks has greatly alleviated this situation. So, I don't know what you know about firebricks? Here we briefly introduce insulating refractory bricks and related knowledge. Hope to help you better understand insulating refractory bricks.

Compared with traditional refractories, the density of ceramic fiber insulation is very low, so its heat capacity is very low (based on the insulation quality in the furnace). With the development of related industries, people's demand for high temperature insulated wool is increasing, and the requirements are also increasing. This requires us to have a deeper understanding of it in order to find its value more. So do you know what kind of material it is? What applications does it currently have? Next, we will introduce to you some high temperature insulation cotton related content, hoping to let you have a deeper understanding of it.

Traditional ceramic fibers are made from inorganic materials, primarily aluminium oxide (Al2O3) and silicon dioxide (SiO2),with very high thermostability. Under normal circumstances standard ceramic fiber can be applied at temperatures up to 1260 °C. By adding small amounts of, e.g., zirconium oxide (ZrO2) the application temperature can be increased to approx. 1600 °C.

Aluminum Melting and holding Furnace Lining construction and baking recommendations1. Mixing: The castable material should be stirred by a forced mixer with a rotation speed of not less than 26 revolutions per minute, dry mixing for 2-3 minutes, then add clean water. The water dosage should be added
