Method for rapidly producing spheroidic boron carbide ceramic powder
The invention discloses a method for rapidly producing spheroidic boron carbide ceramic powder, which comprises the following steps: proportioning a carbon source and a boron source according to the mass ratio of 1: 2.8, putting the proportioned powder into a ball mill, and uniformly mixing for 12-16 hours at the rotating speed of 100-300 r/min; and taking out the ball-milled and mixed powder, drying, carrying out spray granulation to obtain 45-100 [mu] m powder, blowing the powder into an induction plasma device, carrying out high-temperature treatment, and collecting to obtain 15-25 [mu] m spheroidic boron carbide powder. According to the method for rapidly preparing the boron carbide ceramic powder, spray granulation is directly subjected to plasma injection to form the spheroidal boron carbide ceramic powder, rapid and efficient preparation of the spheroidal boron carbide powder is achieved, the purity is larger than 98%, fluidity is good, hardness is high, ceramic forming is convenient, and the method can be used in the field of ceramics. And moreover, the rapid plasma injection method adopted by the invention is more environment-friendly and efficient.
本发明公开了一种快速生产类球形碳化硼陶瓷粉体的方法，包括以下步骤，将碳源与硼源按照质量比1：2.8配料，将配料的粉体置入球磨机中混合均匀，球磨时间为12‑16h，转速为100‑300r/min；将球磨混合后的粉体取出烘干，喷雾造粒得到45‑100μm粉体，将粉体喷吹进入感应等离子体装置，高温处理后，收集得到15‑25μm类球形碳化硼粉体。本发明提供了一种快速制备碳化硼陶瓷粉体的制备方法，该方法将喷雾造粒直接等离子体喷吹形成类球状碳化硼陶瓷粉体，实现了快速高效率的类球形碳化硼粉体制备，纯度大于98％，流动性好，硬度高，便于陶瓷成型，可用于陶瓷领域，也可直接用作热喷涂原料，且本发明采用的快速等离子喷吹法更加环保高效。
