説明
To apply glass-like carbon (GC) to precision die for press-molding of optical glass lens, the wettability between optical glasses and the GC materials was investigated in nitrogen, argon or air atmosphere heated up to 900-1050°C. The GC material calcinated at about 2000°C (GC20) exhibited larger contact angle than that of the GC materials calcinated at 1300°C or 3000°C. This was caused by that calcination at 1300°C or 3000°C promoted graphite reaction of the GC materials. When the contact angle between the GC20 material and some commercial glasses with different chemical composition was compared, kron (Crown) glass achieved the same large contact angle as flint glass. In the kron glass, lower adhesion or more melted fragment of glass was also observed on the GC20 surface. It was expected that a lack of PbO, Na2O and K2O brought on good characteristics of the kron glass.
