How does aluminum dihydrogen phosphate improve the strength and thermal shock resistance of corundum products?

 The high-purity and high-strength corundum brick developed by Luoyang Refractory Research Institute of China adopts the technical route of high-purity fused corundum and sintered corundum clinker made in China, introducing part of activated A12O3 ultrafine powder and sintering at high temperature, and obtains good quality products.


They also added an additive which can activate A12O3 crystal lattice on the basis of introducing micro powder to promote sintering and effectively improve the strength and thermal shock resistance of products. Therefore, using this product under the conditions of severe scouring and frequent thermal shock shows its advantages.


 The corundum products combined with phosphoric acid or aluminum dihydrogen phosphate have hardened the adobe to 300°C, A1PO4 has dewatered the adobe, new compounds are formed at 300 - 400 C, polymerization and polycondensation occur to form macromolecules, dehydration at 800°C is basically completed, aluminum phosphate at 1300~1500°C is basically converted into a lattice structure similar to square Shi Ying type, P2O5 is decomposed and lost, sintering occurs at the same time, aluminum metaphosphate glass appears, and a small amount of impurities in the adobe also form liquid phase, thus further improving the strength of the products.


yucai chemical Factory specializes in the production of sodium hexametaphosphate, sodium pyrophosphate, sodium tripolyphosphate, disodium hydrogen phosphate, industrial phosphoric acid, trisodium phosphate, aluminum dihydrogen phosphate, solid aluminum dihydrogen phosphate, liquid aluminum dihydrogen phosphate, Phosphate series such as sodium dihydrogen phosphate has been continuously pursued and developed for more than 30 years. It has established a good cooperation and sharing relationship with many universities through skilled chemical technology and product development, equipment renewal, and in the chemical industry.
