Abstract
An Aluminum nitride ceramic and preparation method thereof. The aluminum nitride ceramic comprises a porous aluminum nitride matrix. A ferrite is loaded on the pore surface of the porous aluminum nitride matrix; and nano nickel particles are loaded on the surface of the ferrite. The preparation method of the aluminum nitride ceramic comprises steps: sintering the aluminum nitride ceramic by pressureless sintering method, depositing the ferrite on pore surface of porous aluminum nitride matrix by hydrothermal method, and loading nano nickel particles on the surface of the ferrite by reduction method. A micro-reactor is provided. So that the technical problems: the preheating time of the micro-reactor prepared is too long, nickel particles fall off from the surface of matrix, and nano nickel particles grow up due to quick and direct temperature rise can be solved.
