Preparation method of foaming ceramic
The invention discloses a preparation method of a foaming ceramic. The preparation method is characterized by comprising the following steps: mixing coal powder into a foaming ceramic blank; preparing the foaming ceramic through the processes of dry milling, granulation, high-temperature sintering, foaming, cooling and the like. The preparation method disclosed by the invention can be used for determining the mixing amount of the coal powder according to the combustion heat value of the coal powder and sintering heat consumption needed by the foaming ceramic blank, thereby providing the heat needed by the high-temperature sintering and foaming of the foaming ceramic mainly through a coal powder internal combustion mode and reducing the production energy consumption and cost. The preparation method disclosed by the invention simplifies the process course by adopting a dry milling process without drying powder, can be used for greatly reducing the production cost by taking the low-cost coal powder as main fuel and belongs to a high-efficiency low-cost foaming ceramic firing technology.
