1. Acid refractory material generally refers to refractory material with SiO2 content greater than 93%. Its main feature is that it can resist the erosion of acid slag at high temperature, but it is easy to react with alkaline slag. Silica bricks and clay bricks are commonly used for acid refractories. Silica brick is a siliceous product containing more than 93% of silicon oxide. The raw materials used are silica, waste silicon brick, etc., which have strong resistance to acid slag erosion, high softening temperature of load, no shrinkage after repeated calcination, and even slight expansion; However, it is easily eroded by alkaline slag and has poor thermal shock resistance. Silica bricks are mainly used in thermal equipment such as coke ovens, glass melting furnaces, and acid steelmaking furnaces. Clay bricks are mainly made of refractory clay and contain 30% to 46% of alumina. They are weakly acidic ᱜᱞᱩᱠᱚᱡᱽ, ᱜᱞᱩᱠᱚᱡᱽ, ᱟᱨ ᱮᱱᱡᱟᱭᱤᱢ ᱨᱮᱭᱟᱜ ᱜᱩᱱ ᱫᱚ 145 mg ᱠᱟᱱᱟ ᱡᱟᱦᱟᱸ ᱫᱚ ᱥᱟᱹᱨᱤ ᱜᱮ ᱵᱟᱝ ᱵᱮᱥ ᱜᱮᱭᱟ᱾
2. Basic refractory materials generally refer to refractory materials containing magnesium oxide or magnesium oxide and calcium oxide as main components. These refractories have high refractoriness and are resistant to alkaline slag. For example, magnesia brick, magnesia chrome brick, chrome magnesium brick, magnesium aluminum brick, dolomite brick, forsterite brick, and the like. Mainly used in alkaline steelmaking furnaces, non-ferrous metal smelting furnaces and cement furnaces.

4. Melt-casting refractory material refers to a refractory product having a certain shape after being melted at a high temperature by a certain method.
5. Neutral refractory refers to refractory materials that are not easily reacted with acidic or alkaline slag at high temperatures, such as carbon refractories and chrome refractories. Some also attribute high alumina refractories to this category.

7. Unshaped refractory material is a mixture of refractory aggregate and powder, binder or additional admixture. It can be used directly or with appropriate liquid. The amorphous refractory is a new refractory material that is not calcined and has a refractoriness of not less than 1580℃.
