Being production manner of the raw materials for the cerium anti-friction material where ignition loss when designates the mixed rare earth salt

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a raw material for abrasives that can be sintered at a relatively low baking temperature, and does not cause abnormal grain growth when used for manufacturing cerium-containing abrasives.;SOLUTION: This is a manufacturing method to produce a raw material for cerium-containing abrasives comprising, as a main component, a mixture of a cerium-containing rare earth carbonate and a cerium-containing rare earth oxide, wherein part of the carbonate is converted into the oxide by calcining at 400-800°C. The baking time is preferably 0.1-48 hours.;COPYRIGHT: (C)2002,JPO
