Si3n4 Silicon Nitride Ceramic Gasket Ring

Silicon nitride heat shields and magnetic rings are mainly used to protect high voltage electrodes and are widely used in the photovoltaic industry.Heat shields and magnetic rings, as well as ceramic rings, are collectively referred to as electrode shields.Silicon nitride electrode protection cover mainly uses silicon nitride insulation, heat resistance and corrosion resistance.Compared with the protective cover of quartz and alumina which is still in use today, the service life of the silicon nitride electrode shield is more than 10 times, and it will not be electrically broken down during use, and will not be heated, nor will it be heated. Will be eroded away. Due to its own stability, in the use of photovoltaic reduction furnaces, the collapse rate of non-human factors is greatly reduced. Silicon Nitride (Si3N4) Characteristics: 1 Good thermal shock resistance 2 Creep resistance 3 Low density 4 High fracture toughness 5 High hardness and wear resistance 6 Electrical resistivity

Silicon Nitride (Si3N4) is 60% lighter than steel but strong enough to survive some of the most demanding applications in a variety of industries. This lightweight, the high-strength ceramic material is used as an alternative to stainless steel, super alloys, tungsten carbides, and first-generation ceramics such as Al2O3 and ZrO2. It offers excellent thermal shock resistance and high fracture toughness, compatibility with nonferrous metal melts, and improved structural reliability compared to other ceramic materials. When extreme conditions like these push equipment to its limits, Silicon Nitride (Si3N4) industrial ceramics deliver high performance where other materials fail. Typically, Heavy-duty diesel engines. Jet engine igniters. Oil wells thousands of feet underground. Applications for silicon nitride include: Foundries Electronics Oil & Gas Automotive Aerospace
