The coil of vape is very important to vape. How to filter out the harmful substances of the e-liquid and the atomization of the e-liquid have a lot to do with the coil!

When vape first came out, vape only had one kind of cotton coil, and with the improvement of technology, ceramic coil cartridges appeared on the market!

What is Porous Ceramic Coil?

Porous ceramic material is a new type of material that utilizes the physical surface. It is a ceramic body with a three-dimensional network skeleton structure that is fired at high temperature and has a large number of three-dimensional interconnected channels inside.

This new porous ceramic material plays an extremely important role in the atomization process of the vape.

The atomizing core used by FOCOL is a ceramic atomizing heating element, which has the characteristics of stable high temperature resistance, safety and easy oil conduction, and can bring a more delicate taste and the advantages of preventing oil leakage.

At present, the microporous ceramic atomizing core is the standard configuration of e-liquid vape.

How Porous Ceramics Are Made

There are many types of porous ceramic materials. Due to the different purposes of use, the properties of materials are also different. Therefore, many different preparation technologies have been gradually developed in recent years. The general preparation process of porous ceramics is granulation, mixing, molding, sintering, etc.

Porous ceramic core manufacturing process

The pore-forming method of porous ceramics mainly lies in the formation of pores during the sintering process. The pore-forming methods include the addition of pore-forming agents, foaming processes, organic foam impregnation processes, and sol-gel processes.

1. Adding pore forming agent process

By adding a pore-forming agent to the ceramic ingredients, the pore-forming agent occupies a certain space in the green body. During the sintering process, the pore-forming agent leaves the matrix to form pores to obtain porous ceramics. Molding methods mainly include molding, extrusion, rolling, isostatic pressing, injection and slip casting. Products are generally referred to as cellular porous ceramics.

2. Organic foam impregnation

Impregnate the ceramic slurry with organic foam, and burn off the organic foam after drying to obtain porous ceramics. This method is suitable for preparing porous ceramics with high porosity and open pores. Products are generally referred to as mesh porous ceramics.

3. Foaming method

The foaming agent is mixed with the clay material, and the clay particles are bonded to each other under pressure. When enough heat is transferred to the inside of the clay particles, the material expands and fills the entire mold. After cooling, the porous ceramic material is obtained. Porous ceramics with various pore sizes and shapes can be prepared, which are generally called foamed porous ceramics.

4. Sol-gel process

Ceramic particles and organic gel are mixed, cleaned and ion-exchanged, and sintered to form a porous ceramic material. The structure, porosity and pore size of porous SiO2 materials can be changed by adjusting the sintering temperature. The sol-gel method is mainly used to prepare microporous ceramic materials, especially microporous ceramic films.

Advantages of ceramic core:

1. Different forming methods can produce products with complex shapes

2. Various pore structures can be prepared

3. Can produce products with high porosity

4. Good sample strength

5. Especially suitable for making products with closed pores

6. Large porosity and high strength

7. Suitable for making microporous ceramics

8. Suitable for making thin film materials

9. The pores are evenly distributed

Disadvantages of ceramic core:

1. Poor distribution uniformity of pores,

2. Not suitable for producing high porosity

3. Products with small pores and closed pores cannot be manufactured

4. The shape of the product is limited

5. Product component density is not easy to control

6. High requirements for raw materials

7. Process conditions are not easy to control

8. Raw materials are limited

9. Low productivity

10. The shape of the product is limited

Among them, the application is more successful, and the more active research is to add volatile or combustible pore-forming agents to the ceramic ingredients, and use these pore-forming agents to volatilize or burn out at high temperatures to leave pores in the ceramic body. According to the pore size, ceramics can be divided into coarse porous products from 1000 μm to tens of microns, microporous products from 0.2 to 20 μm, and ultramicroporous products from 0.2 μm to several nanometers.

According to the method of pore formation and voids, porous ceramics can be divided into: foam ceramics, honeycomb ceramics, granular ceramics.

The precise control of the preparation technology on the structure of porous ceramics, including the size, shape and distribution of the affected pores, has different effects. The connection strength between aggregate particles determines the strength of porous ceramics, and the relationship between porosity and strength needs to be reasonably coordinated.

Due to high porosity, low density and low thermal conductivity, porous ceramics have huge thermal resistance and small volumetric heat capacity. Porous ceramic materials have been used in various fields such as metallurgy, chemical industry, environmental protection, energy, and biology. In addition to the space shuttle shell insulation, missile heads, and filters that we generally know, they are also playing a huge role in the field of vape.

At present, people use ceramic cores as the standard configuration of high-quality vape pods. But there are also many users who say that ceramic cores are not as good as cotton cores. In fact, both have their own advantages and disadvantages.
