摘要:
A diamond sintered product having diamond particles sintered with a suitable sintering aid is the most suitable as the material for the mold for optical element molding, because it has in combination the advantage of diamond that no fusion with glass at high temperature occurs and oxidation occurs with difficulty to give rise to no precipitation of lead, an appropriate hardness and also the advantage that mirror polishing is possible. "There is also disclosed a mold which has a diamond layer having a (100) face, made by the CVD method utilizing gas having 1-3% methane in hydrogen."
