The preparation process of honeycomb ceramics mainly includes the following steps:

1. Raw material preparation: choose suitable ceramic raw materials, usually including clay, quartz, feldspar, etc., and prepare them in a certain proportion.

2. Formation of ceramic embryo: The formulated ceramic raw materials are stirred and mixed with water to form a uniform slurry. Then, 

through injection moulding, extrusion, pressing and other processes, the slurry ceramic raw materials will be made into ceramic bodies with specific shapes and sizes.

3. Drying: The ceramic body is dried naturally or heated to remove the water in the body.

4. Firing: The dried ceramic body is fired at high temperature to make it have specific physical and chemical properties.

5. Cooling: The fired honeycomb ceramics are cooled naturally or forcibly.

6. Processing: The cooled honeycomb ceramics are subjected to necessary processing, such as cutting, grinding, etc., to obtain the desired shape and size.

In addition, the preparation process requires attention to the following points:

The purity and particle size of the raw materials have a great influence on the performance of the honeycomb ceramics, so we should choose raw materials with high purity, 

low impurities and uniform particle size distribution.

Pay attention to the ratio of various raw materials when batching to ensure that the performance of cellular ceramics meets the requirements.

In the process of forming the ceramic embryo, it is necessary to control the viscosity of the slurry, density and other parameters to ensure the quality of the embryo.

The firing temperature and time have a great influence on the performance of honeycomb ceramics，

so it is necessary to make a reasonable choice according to the specific raw materials and process conditions.

The cooling speed also has an effect on the structure and properties of the honeycomb ceramics, so it is necessary to control the cooling speed in order to obtain the best ceramic properties.
