CERAMIC COMPOSITE, RADOME FOR MISSILE, METHOD FOR PRODUCING CERAMIC COMPOSITE, AND METHOD FOR PRODUCING RADOME FOR MISSILE
PROBLEM TO BE SOLVED: To obtain a ceramic composite excellent in both of thermal impact resistance and electric wave directivity and used for a radome for a missile.SOLUTION: Provided is a ceramic composite 10 used for a radome for a missile. The ceramic composite 10 contains: a ceramic sintered compact 20 essentially consisting of SiN; and a metal oxide layer 30 formed on at least either surface 20a of the ceramic sintered compact 20. The thickness of the metal oxide layer 30 is 10-500 μm. The metal oxide layer 30 includes an amorphous phase.SELECTED DRAWING: Figure 1
【課題】耐熱衝撃性及び電波指向性の両方に優れる、飛翔体用レドームに用いることが可能なセラミック複合体を得ること。【解決手段】セラミック複合体１０は、飛翔体用レドームに用いられる。セラミック複合体１０は、Ｓｉ３Ｎ４を主成分とするセラミック焼結体２０と、セラミック焼結体２０の少なくとも一方の表面２０ａに形成された金属酸化物層３０とを備える。金属酸化物層３０の厚みが、１０μｍ以上でかつ５００μｍ以下である。金属酸化物層３０が、非晶質相を含有する。【選択図】 図１
