Here you will find the detailed specs of materials used & explanations as to why.
Ceramics – Since the invention of the light bulb, ceramics have been consistently researched, experimented with, and systematically enhanced. A precise definition of the term "ceramic" is very limited as the different families of ceramics are produced from a wide variety of chemical substances. Each substance is specifically chosen due to the distinctly different properties (giving the designer the opportunity to choose the right tool for the job). In general however, all ceramics share the following: non-metallic, inorganic, temperature-resistant material that is 30%+ crystalline, and difficult/impossible to dissolve in water.
Ceramics CCA uses are: Silicone Carbide (SiC)
Silicone Carbide (SiC) - SiC is an advanced ceramic material that is a perfect combination of strength and grace: while it is the lightest ceramic currently available, it also boasts the hardness of diamonds. Silicone Carbide is unmatched in thermal conductivity; it retains its strength at high temperatures; and it is also toxicologically safe and chemically pure – all properties which make this versatile material utilized in a vast array of industries.
Sapphire – Sapphire is a single crystal form of Aluminum Oxide (Al2O3). Sapphire is prized for its durability and erosion/corrosion resistance while experiencing extreme temperatures. This gem is second only to diamonds in terms of hardness and resistance to scratches, which attest to its resistance to wear, corrosion, and abrasions. In addition to these attributes, sapphire is extremely thermally stable and boasts a thermal conductivity that is superior to both quartz and titanium. The combination of these and so many more properties make Sapphire the preferred material for high performance systems and components.
Quartz – The chemical purity of fused quartz renders it superior to other types of glass: fused quartz is not only much more durable than borosilicate glass, it also has a higher level of shock resistance and has an incredibly low coefficient of expansion. Fused quartz is extremely chemically resistant and durable, being able to withstand extreme heat without softening or expanding. The combination of chemical purity with superior thermal properties make Quartz an optimum choice over Titanium for connoisseurs who wish to enjoy a more pure, full flavor.
Titanium Grade 2 – The first four grades of Titanium (Grades 1 – 4) are all considered “Commercially Pure”, the only major difference being the small amount of oxygen added. Grade 2 Ti is the most widely used of the four and as such is found in a wide variety of applications. The bio-compatibility and corrosion-resistance is so excellent that many companies regularly use Grd 2 Ti when direct contact with human tissue/bone is required.
