Cerium Hlau, yog siv rau hauv steel foundries kev lag luam los ua FeSiMg alloy thiab nws yog siv los ua ib qho additive rau hydrogen cia alloy. Cerium Hlau tuaj yeem ua tiav rau ntau yam duab ntawm ingots, pieces, xov hlau, foils, slabs, rods, thiab discs. Cerium hlau yog qee zaum ntxiv rau Aluminium los txhim kho Aluminium's corrosion kuj.
