CCELL® hardware utilizes a porous ceramic heating element because of the advantages in terms of uniformity in heating and taste improvement. At the nano to micron scale under a microscope, ceramic has massive pores, superior absorptive properties and high mechanical strength. It is used in the biomedical industry for skeletal and dental prosthetics, in the chemicals industry for facial masks and toothpastes, as well as in water filters and purifiers across a range of applications. Collectively, porous ceramic has been applied to food, pharmacy, biomedicine, spaceflight, environmental protection and new energy production industries, as examples.
Due to its long use in food and medical sciences, ceramic has gained both popularity and a deserved reputation for performance in the vaping industry. Porous ceramics at the micron level allow for vaporizable fluid such as THC/CBD distillate to fill the open cavities of the material allowing for better absorption and application of heat. Ceramic also has high heat conductivity, absorbing and dispersing heat in an effective way which reduces the possibility of detrimental aldehydes from forming.
Operating temperatures of vaping devices generally reach approximately 320°C, a much lower temperature than the over 1,000°C used in the sintering process — the application of heat to form the ceramic. This ensures that there is no chemical or structural change to the ceramic when used for vaporization, making it more reliable and durable. The ceramic production process includes mixing, molding, pore forming, foaming, sinter molding and ultrasonic cleaning to remove any micro-dust generated by the fabrication.
The raw material used in the sintering stage of the ceramic coil of CCELL® vaping devices is food grade inorganic salt powder composed of many abundant elements found on earth such as O, Si, Al, Fe, etc. without any heavy metal elements. No heavy metal elements present on the ceramic is confirmed by RoHS security inspection performed by a third-party after sintering. The inter-granular bounding force of the ceramics increases with the high temperature of the sintering process.
Since the temperature of the vaping device in working condition is so much lower than that of the sintering process used to form the ceramic, and because the inhalation time is usually less than 10 seconds in duration, this process does not generate enough heat and is not of a sufficient time frame to alter the structural or mechanical properties of the ceramic. The micron-sized ducts in the ceramic allow it to easily diffuse the heat, thereby uniformly reducing heat stress in the case of localized overheating.
The oxidation of the ceramic coil does not produce a chemical reaction with vaporizable fluid because of its chemical inertness. The strength of the ceramic has been found to drop by only 3% after immersion in e-liquid for 3 months, at temperatures of 200°C. Also, the force and wind speed of the inhalation is so low that it cannot break or modify the structural integrity of the ceramic.
Viscosity is the measure of substance resistance to motion or flow under an applied force and is expressed as Centipoise (cP). The viscosity of cannabis oil is influenced by the CBD, THC and terpene content in the oil. Distillate usually contains mainly cannabinoids with the highest concentrations of up to 80-90%, whereas live resin has concentrations closer to 40-50%. The principal difference between distillate and live resin is that the latter is frozen wet after harvest, while flower is dried and cured in distillate production. Viscosity also has an impact on the power and heat required to evaporate the liquid in the vaporizer. A formulation with a viscosity outside of design specifications for a given device can cause clogging of the cartridge or vaporizer. The viscosity of a formulation may also change over time depending on how the oil is kept.
