Method for increasing the strength and density of lead titanate ceramic bodies |
| 摘要 |
Strengthened and densified ceramic bodies are produced by hot pressing lead titanate powder into a lead titanate ceramic at a pressure from 1000 to 5000 psi and at a temperature from 700 to 1100 DEG C if the atmosphere is reducing or from 700 to 1200 DEG C if the atmosphere is oxidizing and by annealing the lead titanate ceramic at a temperature from 600 to 1100 DEG C in an oxidizing atmosphere for at least four hours.
