1. Chemical Composition: Cov tub ntxhais ntawm calcium silicon silicon cored hlau yuav tsum muaj cov ntsiab lus calcium silicon siab kom txo qis oxidation.
2. Mechanical Strength: Cov calcium silicon silicon cored hlau yuav tsum muaj lub zog txhua yam kom muaj zog tensile thiab compressive zog thaum lub sij hawm tsim khoom.
3. Corrosion Resistance: Cov calcium silicon silicon cored hlau yuav tsum muaj corrosion kuj zoo los tiv thaiv cov tshuaj tiv thaiv nrog molten hlau ntawm qhov kub thiab txias.
