Example Embodiment
[0006] Example 1
[0007] A kind of nano-ceramic, the raw materials in the formula are composed of aluminum nitride 5%, boron nitride 1%, diatomaceous earth 1%, nano-zirconia 5%, glass fiber 3%, carbon fiber 2%, nano Zirconium dioxide 1%, magnesium oxide 11%, gallium oxide 5%, nano-zinc oxide 3%, alumina 3%, polyvinyl acetate 3%, tungsten carbide 5%, at this time nano-ceramics have better strength and hardness. But the high temperature resistance is poor.
Example Embodiment
[0008] Example 2
[0009] A nano-ceramic. The raw materials in the formula are composed of 15% aluminum nitride, 5% boron nitride, 10% diatomaceous earth, 15% nano-zirconia, 9% glass fiber, 3% carbon fiber, and nanometer. Zirconium dioxide 5%, magnesium oxide 19%, gallium oxide 7%, nano zinc oxide 5%, aluminum oxide 5%, polyvinyl acetate 9%, tungsten carbide 18%, at this time nano ceramics have better high temperature resistance. But its strength and hardness are poor.
Example Embodiment
[0010] Example 3
[0011] A kind of nano-ceramic, the raw materials in the formula are composed of aluminum nitride 5.5%, boron nitride 3.5%, diatomaceous earth 10%, nano-zirconia 5.5%, glass fiber 3.9%, carbon fiber 2.3%, nano Zirconium dioxide 1.5%, magnesium oxide 11.9%, gallium oxide 5.7%, nano zinc oxide 3.5%, aluminum oxide 3.5%, polyvinyl acetate 3.9%, tungsten carbide 5.8%. At this time, nano ceramics have high hardness and high strength , Excellent performance such as high temperature resistance.

Abstract
The invention relates to nanoceramic. The nanoceramic is prepared from raw materials in a formula in percentage by weight as follows: 5%-15% of aluminum nitride, 1%-5% of boron nitride, 1%-10% of diatomite, 5%-15% of nano zirconium oxide, 3%-9% of glass fiber, 2%-3% of carbon fiber, 1%-5% of nano zirconium dioxide, 11%-19% of magnesium oxide, 5%-7% of gallium oxide, 3%-5% of nano zinc oxide, 3%-5%of aluminum oxide, 3%-9% of polyvinyl acetate and 5%-18% of tungsten carbide. The nanoceramic prepared with the method has good properties of high hardness, high strength, high-temperature resistanceand the like and can meet the following manufacturing and processing requirements of ceramic materials.
Description
technical field [0001] The invention relates to a ceramic, in particular to a nano ceramic. Background technique [0002] With the development of society and the advancement of science and technology, nanotechnology has been more and more widely used, and nano-ceramics have emerged as the times require, hoping to solve the fragile problem of ceramics. The existing nano-ceramics have relatively low hardness, strength, and high temperature resistance. Poor, unable to meet the subsequent manufacturing and processing requirements of ceramic materials. Contents of the invention [0003] In view of the above-mentioned problems in the prior art, the present invention provides a nano-ceramic, which can improve hardness, strength and high temperature resistance. [0004] In order to achieve the above object, the present invention is achieved through the following technical solutions: a nano-ceramic, the raw materials in the formula are composed of 5-15% by weight of aluminum nitri...
