Nebulization is the process of converting liquids into fine droplets. Nebulization devices are now widely prevalent in daily life. Humidifiers, facial steamer devices, mist generators, medical nebulizers, and similar products are household practical tools that significantly enhance our quality of life.

With technological advancements, atomization methods have become increasingly diverse, including high-pressure gas atomization, ultrasonic atomization, microwave heating atomization, resistance heating atomization, and others. As the "heart" of atomization technology, the atomization core determines both the atomization performance and user experience. Today, ceramics are gaining prominence in this field, becoming the standard for high-quality atomization cores. So what is the principle behind ceramic atomization? What advantages do ceramic materials offer? In this article, we will explore these mysteries in detail.

I. Why is ceramic selected as the material?

Ceramics are not the only material used for the atomization core in electronic vaporizers.

Materials such as fiber rope, organic cotton, and non-woven fabric have been utilized in the fabrication of atomization cores. The ceramic employed in these cores differs from the conventional ceramics commonly found on dining tables; it is a specialized "porous ceramic."

This is a photograph of the ceramic material magnified by tens of thousands of times. Within a single ceramic core, there are approximately hundreds of millions of such micro-nano pores. This small piece of ceramic material, densely perforated with micro-pores, combined with a metal film, constitutes the core component of an electronic atomizer.

The primary component of the ceramic atomization core is derived from natural sources. Through high-temperature sintering, numerous fine micropores are formed internally, with an average pore diameter equivalent to one-fifth that of a human hair.

These minute micropores are crucial for the ceramic atomization core to achieve stable liquid delivery and retention. Due to surface tension and capillary action, liquids can diffuse uniformly into the core and adhere to its surface. Similar to activated carbon, porous ceramic materials exhibit strong adsorption capacity along with excellent biocompatibility—key factors in selecting ceramics as carriers. Such materials find extensive applications in daily life, including filter cores in water purifiers, refrigerator deodorants, facial masks, toothpaste, and other personal care products.

II. What are the advantages of ceramic atomization cores?

Compared to atomization cores composed of other materials, such as heating wires and fiber ropes or heating wires and organic cotton, ceramic atomization cores offer the following advantages: during heating, their temperature rises more rapidly, exhibits superior temperature uniformity, and allows for more precise temperature
range control. This significantly reduces the generation of aldehyde and ketone compounds during use, thereby ensuring safety.

To ensure optimal atomization for each product, SONG VAPE selects the most suitable heating element based on the vaporizer design and the specific e-liquids used: The Y815 cartridge (CO2) and A36 series employ ceramic heating elements—ceramic components sintered at high temperatures into a bowl-shaped structure, with an S-shaped heating film attached to the surface, resembling the relationship between a cooking pot and stove. As the core component of the atomizer, the heating element uniformly heats the liquid during operation, producing fine vapor.

The heating temperature of the atomization core directly impacts the suction experience of electronic vaporizers. The SONG ceramic atomization core ensures uniform heating, effectively preventing localized carbonization. Combined with the liquid-conducting properties of ceramics, this design significantly reduces the industry-wide challenge of "burnt odor."

In fact, atomization technology has long been applied in medical and other fields, such as asthma treatment. During conventional atomization, the particle size distribution is quite broad. Particles larger than 2.5 μm tend to deposit in the respiratory tract and oral cavity, while particles of 1 μm or smaller are inhaled into the lungs, where their active ingredients are rapidly absorbed. Currently, the atomized particles produced by SONG VAPE ceramic atomization cores are generally smaller than 1 μm, resulting in a superior taste and greater satisfaction.
