    Silicon nitride ceramic material resources in electronics, military and nuclear industry also has wide application:
    Silicon nitride ceramic powder physico-chemical properties and product specifications
    Silicon nitride ceramic is a white-gray powder formula: SI3N4;
    Molecular Weight: 140.3, density 3.2g/cm2
    Its chemical composition: N> 38-39; 0 <1-1.5; C <0.1; Fe <0.2.
    Size according to user requirements.

    Full ceramic bearing rings of silicon nitride and silicon nitride rolling elements (Si3N4) ceramic materials, maintaining PTFE, nylon 66, polyether imide, zirconia, silicon nitride, stainless steel or special aviation aluminum.
    Silicon nitride ceramic bearings Features:
    1, High speed: a cold, mechanical flexibility of small, anti-stress, poor thermal conductivity, light weight, low friction, etc., can be applied to 12,000 rev / min to 75,000 rev / min high-speed spindles and other precision equipment in;
    2, temperature: material itself has a high temperature degrees 1200 ℃, and good self-lubrication, temperature at 100 ℃-800℃temperature difference between the result does not produce a result of inflation. Can be used in furnaces, manufacturing plastic, steel and other high temperature equipment;
    3, anti-corrosion: corrosion-resistant material itself has the characteristics, can be applied to acids, alkalis, inorganic and organic salts, water and other fields, such as: plating equipment, electronic equipment, chemical machinery, shipbuilding, medical equipment and so on.
    4, shielded: do not smoke because of non-magnetic dust, can reduce the bearing off in advance, and big noise. Available in the demagnetization device. Precision instruments and other fields.
    5, the electrical insulation: resistance force high arc injury-free bearings, available in a variety of electrical equipment insulation requirements.
    6, the vacuum: Because ceramic materials with unique self-lubricating properties of the oil, in an ultrahigh vacuum environment, silicon nitride ceramic bearings can not be achieved to overcome the plain bearing lubrication problems.
