Molybdenum disilicide bubbling tubes commonly have diameters of 14, 16, and 20; pore sizes range from single-hole to nine-hole, with 4-hole and 9-hole being the most commonly used; lengths vary between 500-1200 mm. The molybdenum disilicide bubbling tubes produced by Zhengzhou Yixin Kiln Co., Ltd. are high-temperature resistant and of high purity. The fine and uniform pore size can filter small impurities in glass, improving the production quality of glass.
     The main component of molybdenum disilicide bubbling tubes is molybdenum disilicide, with the chemical formula MoSi?, belonging to a tetragonal crystal structure. It is an intermediate phase in the Mo-Si binary alloy system with a high silicon content, appearing gray with a metallic luster. It possesses high-temperature resistance, excellent oxidation resistance, electrical conductivity, thermal conductivity, and certain mechanical properties, making it an ideal material for manufacturing high-temperature heating elements, thermocouple protection tubes, and bubbling tubes. Similar to silicon molybdenum rods, molybdenum disilicide products themselves do not have high-temperature oxidation resistance. Instead, in high-temperature oxidizing atmospheres, a dense, high-melting-point silicon dioxide protective film forms on the surface of the molybdenum disilicide bubbling tube, which prevents further oxidation. Properties of molybdenum disilicide bubbling tubes:
Density: 5.5-5.6 kg/cm3     Porosity: 5%     Water absorption: 1.2%     Vickers hardness: (HV) 570 kg/mm2.

       Molybdenum disilicide bubbling tubes are also cermet products. During installation and use, collisions and external forces should be avoided. Bubbling tubes are also available in other materials, such as tungsten bubbling tubes, glass bubbling tubes, and molybdenum bubbling tubes. Our company primarily produces molybdenum disilicide bubbling tubes. Welcome to inquire.
