Description of Sintered Microporous Alumina Carbon Brick:
Sintered microporous alumina carbon brick not only has excellent alkali corrosion resistance and titanium slag corrosion resistance, but also non-wetting with slag and high-temperature molten liquid.What is more, it have excellent thermal shock resistance, high strength and excellent oxidation resistance.
