Ceramic beads with smooth surface and manufacturing method thereof |
| abstract |
SUMMARY OF THE INVENTION An object of the present invention is to provide a method for producing ceramic beads for obtaining ceramic beads of smooth surface by a simpler method without using a complicated process including, for example, a DC plasma / high frequency plasma combination or a two-stage high frequency plasma. It is. Another challenge is to provide ceramic beads. TECHNICAL FIELD This invention relates to the technique which collects the ceramic beads obtained after putting the preheated ceramic raw material into the laminar flow thermal plasma acquired using the high voltage type direct current (DC) plasma gun, and cooling and solidifying. The ceramic raw material is preheated by passing the furnace through which the heat resistant tube passes while sending the ceramic raw material to the carrier gas, and the preheated raw material powder is introduced into the thermal plasma, and the ceramic beads are released from the thermal plasma at a discharge angle of 60 ° or more with respect to the thermal plasma. It is preferable to perform thermal plasma treatment under the condition that is discharged. Thus, good ceramic beads with a smooth surface and few crack defects or internal void defects are obtained. |
