- Platinum materials are generally used as constituent materials for apparatuses (such as a stirring tank, a dissolution tank, and a clarification tank) for producing high-quality glass such as optical glass and display glass. Platinum is used as a constituent material for these tower tanks because platinum does not deteriorate because it does not form an oxide layer in the atmosphere with a high melting point, and it is less likely to be deformed or damaged during operation. In addition, it has excellent chemical stability and is less likely to contaminate molten glass. As this platinum material, platinum alloys such as platinum rhodium alloy are widely used in addition to platinum (as for the platinum material applicable to the glass industry, details are given in the conventional technology column of Patent Document 1. ) O
