Powder metallurgy
Powder metallurgy is the process of producing metal powders or using metal powders (or mixtures of metal powders and non-metal powders) as raw materials, forming and sintering them to manufacture metal materials, composite materials, and various types of products. Powder metallurgy has similarities with the production of ceramics, both belong to powder sintering technology. Therefore, a series of new powder metallurgy technologies can also be used for the preparation of ceramic materials.
The temperature that the sintering furnaces used in the powder metallurgy industry can withstand is not too high (usually below 1280 ℃), but they need to undergo rigorous rapid cooling to rapid heating tests, and it is usually a reducing atmosphere. Therefore, its kiln furniture material is different from the general cordierite-mullite materials used in the ceramic industry.
The cordierite-mullite is a composite material composed of cordierite, mullite, and glass phases. The product has good thermal shock resistance, high surface smoothness, no slag shedding, low iron content, stable chemical properties, and does not pollute the product. It is particularly suitable for high-purity powder firing.
