Claims15
An X-ray analyzing crystal exhibiting good deterioration resistant qualities, comprising:
- (a) an acid phthalate crystal having a first surface and
- (b) a layer disposed at at least said first surface and having a thickness not exceeding about 2,000 A, said layer consisting essentially of a material selected from the group consisting of a metal and metalloid, said metal and metalloid being substantially chemically inert to the ambient atmosphere.
An X-ray analyzing crystal exhibiting good deterioration resistant qualities, comprising:
- (a) an acid phthalate crystal having a first surface and
- (b) a layer disposed at at least said first surface and having a thickness not exceeding about 2,000 A, said layer consisting essentially of a material selected from the group consisting of aluminum, gold, and carbon being substantially chemically inert to the ambient atmosphere.
An X-ray analyzing crystal exhibiting good deterioration resistant qualities, comprising:
- (a) an acid phthalate crystal having a first surface and
- (b) a layer disposed at at least said first surface and having a thickness not exceeding about 2,000 A, said layer consisting essentially of a material selected from the group consisting of mixtures and alloys of at least two of aluminum, gold and carbon being substantially chemically inert to the ambient atmosphere.
An X-ray analyzing crystal exhibiting good deterioration resistant qualities, comprising:
- (a) an acid phthalate crystal having a first surface and
- (b) a layer disposed at at least said first surface and having a thickness not exceeding about 2,000 A, said layer consisting essentially of a material selected from the group consisting of alloys and mixtures containing at least one of aluminum, gold and carbon being substantially chemically inert to the ambient atmosphere.
An X-ray analyzing crystal exhibiting good deterioration resistant qualities, comprising:
- (a) an acid phthalate crystal having a first surface and
- (b) a layer disposed at at least said first surface and having a thickness not exceeding about 2,000 A, said layer comprising at least two sub-layers, a first sub-layer being disposed on said first surface and a second sub-layer being disposed over said first sub-layer, said second sub-layer consisting essentially of a material selected from the group consisting of a metal and metalloid, said metal and metalloid being substantially chemically inert to the ambient atmosphere, and said first sub-layer consisting essentially of a plastic material providing adherence between said first surface and said second sub-layer.
