Due to the even performance in high temperature, Si3N4 is a commonly used ceramic material in the metallurgical industry. It has excellent thermal shock resistance due to the microstructure. Nextgen Advanced Materials supplies the Silicon Nitride Plate with high quality and fast delivery. Meanwhile, the customization is available.
Find a huge selection of Silicon Nitride Plate from US at Nextgen Advanced Materials INC. Provide professional after-sales service and the right price, looking forward to cooperation. Silicon nitride plate is an inorganic material ceramic that does not shrink during sintering. The strength of silicon nitride, especially hot-pressed silicon nitride, is one of the hardest substances in the world. Si3N4 plate & sheet is a covalent bond compound with high strength, low density, and high-temperature resistance.
