Description:

Technical advanced ceramics play important roles in various industries, Although most of advanced ceramics are well known as excellent materials’ solutions because of their High Hardness/High Wear & Corrosion Resistance/High Temperature Resistance/Chemical Inertness/Electrical Insulation/Non-magnetic, all of them are brittler when compared to metal. However, Ceramic Blades are still choices for some special applications, where require blades with the aforementioned properties, like the paper and film conversion industries, medical and pharmaceutical applications…

Considering that Yttria Stabilized Zirconia has the highest fracture toughness among technical ceramics, ZrO2 is chosen as the material of cutting blades.

Ceramic blades are made out of zirconium oxide which has a hardness level second only to diamonds. The process begins with the extraction of natural zirconium mineral from the earth which is then milled into a fine sand-like consistency.  For our SICER Ceramic knives we chose zirconium #4 which is the highest grade becuse its particles are 30% finer than any other grade of zirconium.  The choice of a premium zirconium material results in a stronger and more durable knife blade without visible flaws, chromatic aberration or micro cracks.  Not all ceramic blades are of equal quality and we have positioned SICER ceramic blades at the top.  SICER ceramic blades have a density that is higher than 6.02 g/cm³ with 30% lower porosity than other ceramic blades.  They undergo exceptional pressure which is then followed by isostatic sintering which renders the blades their signature matte color.  Only the very best quality materials become part of our blades.
