The problems such as elevated temperature strength is inadequate, deformation, in some instances it may even be possible to cause itself and platinum crucible adhesion, cause bigger economic loss.
At present, glass factory when producing high-quality high temp glass mostly using precious metals pt, Rh and its alloy system
Into bubbling pipe, because high temperature causes bubbling pipe deformation serious, using must dismantle progress cold repair shaping after a period of time.
Tube wall thickening to 2 is generally arrived 3mm by some producers in order to extend bubbling pipe service life, and this can alleviate to a certain extent
Deform caused by high temperature, but can not solve Pt, Rh and its alloy high temperature deformation from root and vaporization at high temperature loses
Shortcoming.Because the defects of crystal grain is seriously grown up occurs when close to 1600 DEG C in platinum, cause its elevated temperature strength and creep resistant
Substantially reduced etc. performance, therefore in high temperature and in the case of bearing certain stress, the life-span of platinum bubbling pipe is very short.
