High-temperature alumina

Basic Information

Name: High-temperature alumina

Brand: Xiguan

Place of Origin: Zibo, Shandong

Appearance: Powder

DN1 products feature uniform shrinkage rates, stable sintered densities, and excellent green body machinability. They are used for cast-film-formed alumina ceramic substrates and slip-cast ceramic products, and are particularly suitable for producing 99.5% filler balls with large diameters (50 mm or more), high densities (greater than 3.8 g/cm³), and low water absorption.

DN2 products feature a loose crystalline structure, good grindability, and ease of sintering, allowing for a reduction in ceramic firing temperatures by 50–100°C. They are suitable for forming ceramics via roll-coating, slip casting, dry pressing, isostatic pressing, and slip casting. They can be used in various wear-resistant ceramic components, high-temperature-resistant ceramic components, electronic substrates, and high-grade refractory products.

DN3 products feature coarse grains and well-defined crystalline morphology, with low reactivity and minimal shrinkage. Ceramic products made from this material exhibit stable shrinkage, high ceramic density, high strength, and excellent wear resistance. They are suitable for various structural ceramics, ceramic seals, and wear-resistant ceramics produced via dry pressing, isostatic pressing, and hot-press casting processes, and can also be used to prepare high-quality alumina ceramic granulation powder.
