Title:
IMPROVEMENT OF GRINDING PARTICLE OF BN OF CUBIC SYSTEM
Document Type and Number:
Japanese Patent JPS59187072
Kind Code:
A
Abstract:
PURPOSE: To improve grinding ability of grinding particles, by heat-treating grinding particles of BN of cubic system in a molten salt at a specific temperature so that impurities are dissolved in the bath without damaging the grinding particles.
CONSTITUTION: Grinding particles of BN of cubic system are heat-treated in a molten salt (preferably water-soluble chloride of NaCl-KCl system) at 500W 1,300°C, preferably 700W1,000°C. The heat-treatment is preferably carried out ≤5°C/min low rate of heating.
