HOLLOW CERAMIC BALL MEMBER, FRAC BALL, HYDRAULIC FRACTURING SYSTEM, AND METHOD OF PRODUCING HOLLOW CERAMIC BALL MEMBER
PROBLEM TO BE SOLVED: To provide a ceramic ball which can be destructed relatively easily with impact such as striking force while having high pressure resistance.SOLUTION: This invention provides a hollow ceramic ball member that is a hollow member having a substantially spherical outer peripheral face, and an inner peripheral face, and is mainly composed of ceramic at least comprising carbon, wherein a carbon content ratio of an outside area comprising the outer peripheral face is higher than a carbon content ratio of an inside area of comprising the inner peripheral face.
【課題】 高い耐圧性を有しつつ、打撃力等の衝撃力で比較的簡単に破壊することができるセラミックボールを提供する。【解決手段】 略球状の外周面と、内周面とを有する中空部材であって、少なくとも炭素を含むセラミックスを主成分とし、前記外周面を含む外側領域の炭素含有割合が、前記内周面を含む内側領域の炭素含有割合に比べて大きいことを特徴とする中空セラミックボール部材を提供する。【選択図】 図１
