NOVELTY - A zirconium oxide ceramic mobile phone backboard comprises 80-90 pts. wt. yttrium stabilized zirconium oxide, 1-3 pts. wt. neodymium oxide, 1-3 pts. wt. graphene oxide and 2-15 pts. wt. organic carrier. The graphene oxide is added into diethanol amine solution to prepare graphene oxide dispersion liquid. The dispersion liquid is mixed with polysilazane solution. USE - Zirconium oxide ceramic mobile phone backboard. ADVANTAGE - The phone backboard has smooth feel, good color, and wear resistant. It is not easy to be broken.
