Refractory Materials for the Building and Sanitary Ceramics Industry
Refractory materials can be categorized by application into: metallurgical refractories, cement refractories, glass refractories, and other refractories. Ceramic refractories are classified as other refractories, while building and sanitary ceramics are a branch of ceramics. Refractory materials are further divided into Read More …
Effect of Preparation Technology on Properties of Magnesia-Chrome Bricks
Different production processes lead to significant differences in the structure of magnesia-chrome materials, which in turn affect the performance of magnesia-chrome bricks. For example, directly bonded magnesia-chrome bricks have good thermal shock resistance, while fused-rebonded magnesia-chrome bricks have strong corrosion Read More …
