Product description：
Redon polycrystalline alumina plate is a kind of rigid polycrystalline alumina fiber product prepared by special process by mixing polycrystalline alumina fiber cotton with inorganic refractory aggregate, inorganic refractory powder and special additives in a certain proportion, which can be processed into rigid special-shaped parts of various shapes and sizes. The main crystalline phases are corundum phase and a small amount of mullite phase.
