1. Industry introduction:
Powder metallurgy is a process technology for preparing metal powder or using metal powder (or a mixture of metal powder and non-metal powder) as raw materials, forming and sintering, to produce metal materials, composite materials and various types of products. Powder metallurgy has similarities with the production of ceramics, and both belong to powder sintering technology. Therefore, a series of new powder metallurgy technologies can also be used for the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solving the problems of new materials and plays a pivotal role in the development of new materials.
Powder metallurgy includes milling and products. Among them, pulverization is mainly a metallurgical process, which is consistent with the word. The powder metallurgy products often go far beyond the scope of materials and metallurgy, and are often cross-disciplinary (materials and metallurgy, machinery and mechanics, etc.) technology. Especially modern metal powder 3D printing, which integrates mechanical engineering, CAD, reverse engineering technology, layered manufacturing technology, numerical control technology, material science, and laser technology, makes powder metallurgy products technology a modern comprehensive technology that spans more disciplines.

3. Specific application:
In the production process of powder metallurgy and ceramics, sintering is an indispensable link. Due to the wide application of powder metallurgy technology, the sintering process selects the heating material to be silicon carbide (silicon carbide heating element) or silicon molybdenum rod (molybdenum disilicide heating element) according to the different sintering temperature. For some industries, due to the particularity of the production process, the heating element is prone to be placed in a relatively harsh environment. For example, other corrosive environments such as strong acids and alkalis and high temperatures will all have different effects on the life of the rod. .
Songshan Electric’s silicon carbide rods arrange special links in the production process to strengthen and transform the rods, so that the rods can be added with different production materials and layer technologies according to the changes in the use environment (or acidic or alkaline), so that the silicon Carbon rods have good resistance in this special environment, effectively slowing down the corrosion of corrosive gases on the rods, thereby maintaining a good heating state and service life.
Songshan Electric’s silicon molybdenum rods (molybdenum disilicide heating elements) are made of the latest international hot bending technology. The silicon dioxide protective film and the pure material of the rod body make the rod body exposed to high temperature and corrosion. Effective protection in the gas. When the furnace temperature is higher than 1700 degrees, Songshan Electric's silicon carbide rods will show better working conditions and long service life.
