Nano powders are particulate materials that exhibit basic structural properties on a scale of 1-100 nm. The field of application of nanopowders is based on their unique properties, such as a very high specific surface area, increased chemical activity of atoms and molecules at the interface, and high absorption. Many of these properties are atoms and molecules on the surface versus the bulk state. Since the properties of nanoparticles are mainly related to their size, it is u

The driving force of refractory industry Refractory solutions are required for all heat-related production processes. The most important industries require suitable refractory applications. Generally speaking, without refractory materials, the industry cannot produce the items that communities desperately need. The strong demand for products in the aerospace, electrical, automotive, glass and cement industries is expected to drive the expansion of the refractory market worldw

Refractory Castables of the new generation A refractory castable is a mixture of heat-resistant aggregate and heat-resistant hydraulic cement; when used, it is mixed with water and tamped or poured into place. The use of refractory castables continued to expand, and the chemical and physical properties continued to improve over time. At first, this was only possible through the expansion and improvement of calcium aluminum cement (CAC). But the real push for refractory castab
