Silicon nitride igniter is a high-temperature heating element made of high-performance silicon nitride (Si₃N₄) ceramic material. It is mainly used in gas equipment to achieve rapid and reliable ignition through electrical heating conversion. It is widely applied in various gas devices, such as household or industrial gas water heaters, gas grills, gas heaters, etc. Moreover, in more specialized fields, such as automotive engines, aerospace, and the starting heating elements of solid oxide fuel cells, it also has important applications.

Frequently Asked Questions
Silicon nitride (chemical formula: Si₃N₄) is an inorganic compound composed of silicon (Si) and nitrogen (N), and it has two crystal forms: α and β. Among them, β-Si₃N₄ has become the mainstream due to its high strength and hardness (Mohs hardness approximately 9). It is a super-hard material in nature with a hardness second only to diamond and cubic boron nitride. It is also an important high-temperature structural ceramic, wear-resistant material and semiconductor packaging substrate material in modern industry.
The silicon nitride powder itself is grayish-white or light-colored. However, after sintering, due to oxidation at high temperatures, the presence of additives, the introduction of dark substances from impurities (such as iron, carbon), and the reduction of pores during sintering and densification, which enhances light absorption, the final products tend to be black.
