How to Make a Fine Ceramic Knife
Image : How to Make a Fine Ceramic Knife Water, raw powder and ceramic milling balls are fed into a mixer-like device called a mill.
   
Image : How to Make a Fine Ceramic Knife To create particles of uniform size, with diameters of approximately one micrometer (1 µm or 0.001 mm), raw materials are first mixed into a slurry — a fluid of water and ceramic powder in which the particles are blended.
   
Image : How to Make a Fine Ceramic Knife A spray dryer dehydrates the raw materials in the slurry to make a granulated powder.
Small grain of 1µm or 0.001mm degree
   
Image : How to Make a Fine Ceramic Knife The granulated powder is used to fill a knife-shaped mold.
   
Image : How to Make a Fine Ceramic Knife The mold is placed under high pressure — 1 ton per cm2 (approx. 12,900 psi) — to solidify the powder into the desired shape.
   
Image : How to Make a Fine Ceramic Knife The material is then fired and sintered in a kiln, like conventional ceramics, but under precisely controlled temperatures.
   
Image : How to Make a Fine Ceramic Knife During the firing process, the ceramic blade shrinks to 75 percent of its original, unfired size, while the volume shrinks by nearly half. These shrinkage rates are carefully calculated during the design process, so the finished size matches the design specifications.
