摘要: A glass substrate manufacturing method advantageously applicable to magnetic recording disk substrates, LCD photomask or optical memory substrates. The is formed by chemically strengthening a immersing the in chemical reinforcement solution heated and then ion exchanging ions on surface layer of with solution; removing from annealing it temperature higher than crystallization molten salt; rapidly cooling at rate which salt deposited prevented; cleaning substrate. Moreover, agent containing acid.
