Conventional fired grindstones containing super-abrasive grains such as diamond and CBN are (Carholanodam) abrasive powder is impregnated with diamond or CBN powder using a vitreous material made of alkali salts such as silicic acid or lime as a flux (bonding bond), and fired.The firing temperature is also high. In the production of grindstones containing diamond, many grindstones containing CBN, which has high thermal stability, are put into practical use because the thermal stability of diamond deteriorates at temperatures above 650°. Impact is inevitable.

セラミック砥石の製造に逍していることが判った。That is, an object of the present invention is to provide a superabrasive ceramic grindstone that can be manufactured using a vortex r11 that does not cause any damage to the immersed nature of diamond or CBNi grains. As a bonding agent, the use of silica fiber glass is unclear, and as a result of research into a clean first-generation temperature bond, we found that the crystal shape is similar to that of linker (Sin2), which can be said to be the prototype of heat-resistant ceramics. It has been found that this glassy aluminum phosphate is used in the production of superabrasive ceramic grinding wheels.
