What is the principle of the reaction of firing porcelain?The principle of firing porcelain was as follows:
1. ** Material preparation **: Choose suitable ceramic raw materials, such as kaolin, porcelain stone, Quartz, etc., and prepare the raw materials into powder or granules by crushing and grinding.
2. Shaping: Using hand molding (such as kneading, wheel molding) or mechanical molding (such as injection molding, squeezing) to give the prepared raw materials the desired shape.
3. ** Dry **: After forming the porcelain products, the moisture in them needs to be removed. It can be naturally dried or heated to ensure that there is no excess moisture inside the product.
4. ** Sintered (burned)**
- ** Pre-burning stage **: The organic matter and moisture in the product will gradually burn and evaporate, and the crystallization and chemical reaction in the raw materials will begin.
- ** Firing stage **: The temperature gradually increases, and the porcelain raw materials will be agglomerated. The particles will combine with each other to form a dense structure.
- ** Cooldown Stage **: Slowly cool the fired porcelain products to avoid internal stress and cracking. The control of temperature, time, and atmosphere during this process was very important. Different porcelain materials and products required different firing conditions.
In the process of firing porcelain, the formation principle of celadon was that the iron dioxide in the body glaze was roasted in a reducing flame atmosphere. Moreover, the phase diagram of different porcelain raw material systems would affect the temperature of the green body and the width of the firing range. For example, the low melting point in the K2O-Al2O3- SiO2 system was low (985 + 20 ° C), and the low melting point in the MGO-Al2O3- SiO2 system was high (1355 ° C). The thermal analysis curve of the blank could also be used as the basis for the formulation of the firing system.
