Silicon molybdenum rod products are made from high-quality raw materials, ensuring uniform heating and strong welding. With a full range of semi-finished specifications, ample stock, fast order processing, dedicated after-sales service, and extensive experience, we provide related technical services.

The voltage of silicon molybdenum rods: At room temperature, the resistance of silicon molybdenum rods is very low and increases rapidly as the temperature rises. Once the temperature stabilizes, the resistance remains constant. However, silicon molybdenum rods have a specific surface load capacity, so the voltage applied to them during heating must be adjusted appropriately and timely. This is why silicon molybdenum rod electric furnaces are equipped with transformers.

The price of silicon molybdenum rods may fluctuate due to changes in raw material costs, such as molybdenum powder. The unit price also varies depending on the model and specifications of the silicon molybdenum rods.

In a high-temperature oxidizing atmosphere, a dense quartz SiO₂ protective layer forms on the surface of the element, preventing further oxidation of MoSi₂. When the element temperature exceeds 1700°C, the quartz protective layer, which has a melting point of 1710°C, melts. Due to surface tension, the molten quartz gathers into droplets and loses its protective function. If the element continues to be used in an oxidizing atmosphere, the quartz protective layer will regenerate.
