Abstract

PURPOSE: To obtain a knife for use in a supermicrotome at cheap cost and capable of withstanding the continuous use of 500 times or more by use of a monocrystal material of alpha-alumina and selecting an angle formed by two faces forming a ridgeline of the edge of a knife between 30°W70°.
CONSTITUTION: The monocrystal of alpha-alumina is produced by the Bernoulli's method or other like method, and is of the same quality as sapphire, ruby or the like. As the face (a) forming the ridgeline 1 of the crystal, the surface c of the crystal is selected, and as the face (b) the surface r of the crystal is selected, and the angle of the edge is formed into 58°. Then, these two faces are ground by mechanochemical polishing using minute particles of SiO2 with a polishing allowance of about 5μ. By this procedure, it is possible to obtain at cheap cost a knife usable in manufacturing a microtome and a supermicrotome.
