Firebrick is a type of brick resistant to heat, pressure, and chemical corrosion<\/strong>, made from special clays and minerals with high melting points<\/strong>. These bricks can withstand extremely high temperatures\u2014sometimes over 1500\u00b0C<\/strong>\u2014without losing their strength, deforming, or melting.<\/p>\n

Raw Materials of Firebrick<\/strong><\/h2>\n

The main components used in firebrick production include:<\/p>\n

    \n
  • \n

    Fire clay<\/strong><\/p>\n<\/li>\n

  • \n

    Alumina (Al\u2082O\u2083)<\/strong><\/p>\n<\/li>\n
