Machinable ceramic and manufacturing method of the same
The present invention relates to machinable ceramics. According to the present invention, the machinable ceramics is manufactured by a method which comprises: a slurry preparing step of preparing slurry by mixing an organic solvent with mixed powder including pyrophyllite, Al_2O_3, MgO, Na_2CO_3, TiO_2, MgF_2 and ZrO_2; a slurry drying step of drying the slurry prepared in the slurry preparing step; a melting step of melting the powder dried in the slurry drying step by treating the powder with heat; a vitrification step of vitrifying a ceramic component molten in the melting step by rapidly cooling the ceramic component at room temperature; a grinding step of grinding the ceramic components vitrified in the vitrification step; and a molding and sintering step of molding a molded article by pressing the powder prepared in the grinding step, and sintering the molded article. According to the present invention, the machinable ceramics has improved thermal expansion characteristics and laser processability which can be applied to a probe card.
본 발명에 따르는 머시너블 세라믹은 연납석과, AlO과, MgO과, NaCO과, TiO과, MgF과, ZrO를 포함하는 혼합 분말을 유기용매와 혼합하여 슬러리를 제조하는 단계(슬러리 제조 단계); 상기 슬러리 제조 단계에서 제조된 슬러리를 건조시키는 단계(슬러리 건조 단계); 상기 슬러리 건조 단계에서 건조된 분말을 열처리하여 용융시키는 단계(용융 단계); 상기 용융 단계에서 용융된 세라믹 조성물을 상온으로 급랭시켜 유리화하는 단계(유리화 단계); 상기 유리화 단계에서 유리화된 세라믹 조성물을 분쇄하여 분말화시키는 단계(분말화 단계); 상기 분말화 단계에서 제조된 분말을 가압하여 성형하고 소결하는 단계(성형 및 소결 단계);로 제조된 머시너블 세라믹에 관한 것이다.
