可磁化磨料颗粒及其制备方法
摘要：
本发明提出了一种制备可磁化磨料颗粒的方法，所述方法包括：用水玻璃润湿陶瓷颗粒的外表面以提供润湿的陶瓷颗粒。使可磁化颗粒与所述润湿的陶瓷颗粒接触，以提供涂有粉末的陶瓷颗粒。将所述涂有粉末的陶瓷颗粒加热到至少足以使所述涂有粉末的陶瓷颗粒的所述可磁化颗粒粘结至相应的所述陶瓷颗粒的温度，从而提供所述可磁化磨料颗粒。每个可磁化磨料颗粒在各自的基础上包括相应陶瓷颗粒，所述相应陶瓷颗粒具有粘结至其上的可磁化颗粒。
摘要（英）：

The invention provides a method of making magnetizable abrasive particles. The method includes: moistening the outer surfaces of ceramic particles with waterglass to provide moistened ceramic particles. Magnetizable particles are contacted with the moistened ceramic particles to provide powder-coated ceramic particles. The powder-coated ceramic particles are heated to at least a temperature sufficient to bond the magnetizable particles of the powder-coated ceramic particles to the respective ceramic particles thereby providing the magnetizable abrasive particles. On a respective basis, each magnetizable abrasive particle comprises a respective ceramic particle having a magnetizable particles bonded thereto.
