Ceramic as well as preparation method and application thereof
The invention relates to the field of ceramic materials, and in particular, relates to ceramic as well as a preparation method and application thereof. The preparation method of the ceramic comprisesthe step of granulating by using ceramic slurry, wherein the ceramic slurry comprises a ceramic powder material and a polycarboxylate water reducing agent; the ceramic powder material comprises one ora mixture of B4C, SiC and Al2O3 and is a single-particle-size material, and D50 is smaller than or equal to 0.5 micron; the weight of the polycarboxylate water reducing agent is 0.18%-0.35% of the weight of the ceramic powder material. According to the invention, the problems of over-adhesion and low solid content of slurry in spray granulation of fine micron single-particle-size powder are solved; the method improves slurry fluidity, fully solves tower blockage caused by stirring dead angles and slurry self-deposition in the later stage of spray granulation, and provides a method with guiding significance for a granulation process of single-particle-size powder ceramics.
本发明涉及陶瓷材料领域，具体涉及一种陶瓷及其制备方法与应用。所述陶瓷在制备时包括使用陶瓷浆料进行造粒的步骤；其中，所述陶瓷浆料包含陶瓷粉体材料和聚羧酸减水剂；所述陶瓷粉体材料包含B4C、SiC和AL203中的一种或其混合物，为单一粒径材料，D50≤0.5μm；所述聚羧酸减水剂的重量为所述陶瓷粉体材料的重量的0.18～0.35％。本发明解决了细微米单一粒径粉体喷雾造粒中浆料过黏，固含量较低的问题，改善了浆料的流动性，充分解决了喷雾造粒后期由于搅拌死角及浆料自身沉积等原因造成的堵塔，为单一粒径粉体陶瓷的造粒工艺提供了具有指导意义的方式方法。
