You will find brief explanations on important technical terms from the area of high-temperature technology in our glossary.
Aluminosilicate wool (ASW), also known as refractory ceramic fibre (RCF), is made up of amorphous fibres that are produced in a melting process of, among others, alumina (Al2O3) and silica (SiO2). The Al2O3 content is between 45% and 55%. The material is usually used at application temperatures of 600°C to 1400°C.
MoSi2 heating elements form a protective SiO2 layer on their surfaces, which prevents oxidation of the basic material. If the SiO2 layer bursts off, regeneration firing at temperatures above approx. 1450°C for several hours can be applied. There should be no products in the furnace for this. Please contact us if you have any questions about regeneration firing.
