The refractoriness of high-quality clay bricks is comparable to that of silica bricks, as high as 1690-1730 °C, but the softening temperature under load is more than 200 °C lower than that of silica bricks. Because in addition to the mullite crystals with high refractoriness, the clay bricks also contain nearly half of the low melting point amorphous glass phase.
1. High-quality clay brick products are divided into three grades: (NZ)-42, (NZ)-40, (NZ)-38 according to physical and chemical indicators.
2. The shape and size of high-quality clay brick products conform to the provisions of GB2992-82 "General Refractory Brick Shape and Size". If there is no brick type required by the buyer in the standard, it will be produced according to the drawings of the buyer.
3. The classification of high-quality clay brick products conforms to the provisions of YB844-75 "Classification and Definition of Refractory Products". Generally divided into standard type, general type, special type, special type, and can also be specially made according to user requirements.

Physical and chemical properties of clay refractory bricks
Ordinary clay refractory bricks are generally 1.8-2.0g/cm3, dense clay refractory bricks are generally 2.05-2.20g/cm3, and high-density clay refractory bricks are generally 2.25-2.30g/cm3
The specifications and sizes of clay refractory bricks will vary according to the use of clay refractory bricks. For example, the specifications and sizes of clay refractory bricks used for walls and those used for ground arches are very different. The density of clay refractory bricks also has a lot to do with its material.
The content of Al2O3 in clay bricks is generally more than 40%, and the content of Fe2O3 is less than 2.0~2.5%. The clinker in the ingredients is 65~85%, and the combined clay is 35~15%. The pulverized bound clay and the finely ground clinker are mixed and ground, and then mixed with the granular clinker to make semi-dry mud, high pressure molding, and sintering at about 1400 ℃, with good performance. Clay bricks are weakly acidic at high temperature, and their ability to resist alkaline slag erosion is slightly worse, but increases with the increase of Al2O3 content. The thermal stability is better than that of silica brick and magnesia brick (see magnesia brick).

The thermal stability is better than that of silica brick and magnesia brick (see magnesia brick).
Specifications of clay refractory bricks
There are two types of refractory bricks, one is shaped refractory material and the other is unshaped refractory material. Refractory bricks are mainly used to build high-temperature building materials and kilns for various thermal equipment. Its types are mainly distinguished by shape and size. The specifications and dimensions of refractory bricks are as follows:
The dimensions of straight refractory bricks are represented by A×B×C (unit: mm)
The dimensions of wedge-shaped refractory bricks are represented by A×(C/D)×B (unit: mm)
The dimensions and specifications of the arch brick are expressed as (L/C)×(A/B)×(E/D) (unit: mm)
Therefore, to determine the specifications of refractory bricks and the size of refractory bricks, it is necessary to determine the characteristics of refractory bricks and its representation.
