The “Ceramic coils, danger and options” thread has been one of my 2019 favorites. My question is are the Dabtabs made of raw materials such as silica powders and pore-forming materials like starch or other organic polymers? @Decarboxylation do you know?
The ceramic coil is made from inorganic porous ceramic material. There are tiny pores inside the ceramic material that cannot be seen. Pores play an important role in wicking. In order to produce a porous ceramic material, raw materials such as silica powders and pore-forming materials like starch or other organic polymers are needed. Then they are mixed and put into a mold with high pressure. Samples are obtained with a fixed shape. The samples are put into a furnace and set to a high temperature. Pores are formed while the pore-forming agent combusts and escapes. This kind of pore plays an important role by introducing e-liquid into your vape. However, to make enough pores, the temperature to stick the materials together is lower which causes low tensile and compressive strength. The powders fall off or crack when the ceramic coil is touched or shaken. All the powders can be introduced into the lung by air which is dangerous (the speed of air can reach 223mph when we are vaping).
