Tabular corundum is a completely recrystallized -al2o3 sintered at slightly below the melting point of imported alumina after batching, grinding and molding. The crystals are arranged in a tabular staggered way, which increases the mechanical strength of the particles. The closed pores were mainly distributed uniformly in and between grains, with high volume density, low apparent porosity and water absorption, which reduced the amount of liquid used for reprocessed products. Application
1) refractory materials, furnace charge, aggregate, castable , rammed miscellaneous materials, plastic, pressing materials, projection materials, spray paint, vibration materials, refractory mud 2) wear-resisting coating, refractory coating, wear-resisting machinery, 3) smelting, casting, steel mills, power plants 4) ceramic deburring , surface treatment 5) firebrick, fireproof ceramics Features 1. Low porosity, low heat shrinkage and good heat load strength 2. high refractoriness, high mechanical strength and abrasion resistance 3. good chemical purity, excellent dielectric properties and good resistance against acid and alkali corrosion. 4. The closed pores were distributed uniformly in and between the grains, with high volume density and low apparent porosity and water absorption. | Size | chemical index | physical index |
