microporous sintered corundum 3-5mm 5-8mm

Product Introduction

Using a special process and numerical simulation optimisation, a microporous sintered alumina with performance comparable to traditional sintered alumina but reduced thermal conductivity was developed and produced, containing more micron and sub-micron closed pores. It has the characteristics of high strength, low thermal conductivity, and good thermal shock resistance.In order to meet the needs of energy saving, the refractory materials used for work lining can reduce heat dissipation without affecting the usability and have been paid attention to. Microporous sintering of raw materials can reduce the weight of refractory products. By reducing thermal conductivity and reducing material structural stress, thermal shock resistance can be improved while maintaining the key properties of the material, which is not only conducive to improving service life, but also reducing heat loss.

Replacing traditional sintered alumina aggregates with microporous sintered alumina in part or all in refractories can provide the following benefits:

• The thermal conductivity of the product is reduced, which is conducive to heat preservation and energy saving.
• It is conducive to reducing material consumption and reducing the weight of the refractory lining.
• The interface bonding between particles and the matrix is enhanced, and the strength and resistance to medium erosion of the product are not reduced.
• The thermal shock resistance of the product can be significantly improved.

Product particle size: Various specifications of granular materials below 15mm are available. Product packaging: 25kg/bag, 1000kg/bag or according to user requirements.
