Embodiment 1

[0013] The present embodiment provides a kind of alumina ceramic for new energy vehicles, the alumina ceramic comprising alumina, silicon carbide whiskers, yttrium stable zirconia, silicon dioxide, titanium dioxide, nickel oxide and strontium carbonate, the weight percentage of each component is as follows: the alumina: 90 ~ 95wt%, the silicon carbide whisker: 2 ~ 5wt%, the yttrium stable zirconia: 2 ~ 5wt%, the silica: 1 ~ 2wt%, The titanium dioxide: 0.5 ~ 1wt%, the nickel oxide: 0.1 ~ 0.3wt, the strontium carbonate: 0.3 ~ 0.8wt%. In this way, the above seven raw materials are mixed together to form a new ceramic material, so that the ceramic parts made have both high strength and high explosion-proof performance. Among them, the silicon carbide whisker is a single crystal fiber, which has a fairly good high temperature resistance and high strength, and is used as a raw material for electronic ceramic parts, which greatly improves the strength of ceramic parts. Yttrium-stabilized...

Embodiment 2

[0015] The present embodiment provides that the alumina ceramic is composed of the following weight components: the alumina: 92 ~ 93wt%, the silicon carbide whisker: 2.5 ~ 4.5wt%, the yttrium stable zirconia: 2.5 ~ 3.5wt%, the silica: 1 ~ 1.5wt%, the titanium dioxide: 0.55 ~ 0.65wt%, the nickel oxide: 0.15 ~ 0.2wt%, the strontium carbonate: 0.35 ~ 0.5wt %.

[0016] The above embodiments of the present invention serial number is for description only and does not represent the advantages and disadvantages of the embodiments.

Abstract

The invention discloses aluminum oxide ceramic for a new energy automobile, which comprises the following components in percentage by weight: 90 to 95 percent of aluminum oxide, 2 to 5 percent of silicon carbide whisker, 2 to 5 percent of yttrium-stabilized zirconium oxide, 2 to 5 percent of silicon dioxide, 2 to 5 percent of titanium dioxide, 2 to 5 percent of nickel oxide and 1 to 5 percent of strontium carbonate. The catalyst comprises the following components in percentage by weight: 1 to 2wt% of silicon dioxide, 0.5 to 1wt% of titanium dioxide, 0.1 to 0.3 wt% of nickel oxide and 0.3 to 0.8 wt% of strontium carbonate. By adjusting the formula of the aluminum oxide ceramic, especially by adding the silicon carbide whiskers, the aluminum oxide ceramic piece prepared from the new material has the strength of 95 aluminum oxide ceramic and also has excellent explosion-proof performance. The material has good adsorbability to a coating on the surface of ceramic, and is an ideal material for high-power and high-current ceramic tubes.

Description

Technical field [0001] The present invention relates to the field of new material technology for electronic ceramics, in particular to an alumina ceramic for new energy vehicles. Background [0002] Ceramics that can use electrical and magnetic properties in the electronics industry are called electronic ceramics. Electronic ceramics are ceramics with new functions that are finally obtained through the control of surfaces, grain boundaries and dimensional structures. It can be widely used in energy, household appliances, automobiles and so on. [0003] At present, electronic ceramics widely used in new energy vehicles, household appliances and other equipment are either not strong or have poor explosion-proof performance, and no electronic ceramic can have excellent explosion-proof performance and high strength at the same time. [0004] Therefore, the invention of an alumina ceramic with both high strength and high explosion resistance has become an urgent problem for those skil...
