Definitions
- Pigments with high chromaticity and temperature stability possessing required color characteristics have traditionally been made from cadmium sulfide, cadmium sulfo- selenide or zinc substituted cadmium sulfo-selenides.
- Tin niobium pyrochlore is formally Sn 2 Nb 2 0 7 .
- the referenced application posits pigments in which tin sulfide is used in lieu of stannous oxide in the synthesis of the finished pigment.
- the referenced patent posits substitution of the pentavalent niobium atoms with other transition metals that can exhibit a high valence state, such as tungsten or molybdenum in the form of Mo0 3 or W0 3 . These substitutions are intended to modify the color of the pigments produced.
- An inorganic pigment comprising tin; a divalent metal; niobium; and an oxysulfide, an oxyselenide, or oxysulfo-selenide
- FIGURE 1 is a UV-visible spectrum for examples 1 -6 when the pigments are printed on Leneta cards out of an acrylic paint vehicle.
- FIGURE 2 is a Kubelka Remission plot for examples 1-6 when the pigments are printed on Leneta cards out of an acrylic paint vehicle.
- FIGURE 3 is a powder x-ray diffraction pattern for example 2.
- FIGURE 4 is a powder x-ray diffraction pattern for example 4.
- FIGURE 5 is a powder x-ray diffraction pattern for example 1 1.
- Inorganic pigments based on tin niobium niobium oxide may be substituted at the location of the tin atom in the lattice to adjust color or improve ease of synthesis.
- stannous oxide equimolar proportion of stannous oxide.
- the temperature at which such decomposition occurs under an inert atmosphere is known to be as low as 300°C when stannous oxide is heated independent of other components.
- stannous oxide is calcined with other oxides with the aim of obtaining a new mixed-metal oxide, such as tin niobium pyrochlore, Sn 2 Nb 2 0 7 , a competition is set up between the desired solid-state ionic diffusion to yield the pyrochlore lattice and undesirable decomposition of the stannous oxide - yielding tin metal and stannous oxide.
- Substitution at the divalent metal center in Sn 2 Nb 2 0 pyrochlore can improve color of the derived pigment, control onset of absorbance in a manner expected for a band-gap colorant, reduce the firing temperature demanded to complete synthesis, and eliminate the requirement to conduct acid washing of the calcined product to rid it of contaminants such as metallic tin.
- the inorganic pigment comprises tin; a divalent metal; niobium; and an oxysulfide, an oxyselenide, or oxysulfo-selenide.
- the pigments has the empirical formula: M 2 Nb 2 Z 7 -XMNb 2 Z 6 where M comprises tin and a divalent metal; Z comprises oxygen and either sulfur, selenium, or a mixture of sulfur and selenium; and X ranges from 0 to 100. In one embodiment, X may be from about 0 to about 0.15; about 0 to about 0.25; about 0.25 to about 0.5; about 0.5 to about 1.0; about 1.0 to about 10; about 10 to about 50; or about 50 to about 100. In the empirical formula M 2 Nb 2 Z 7 -XMNb 2 Z 6 , X is a coefficient.
- Divalent metals are those where the common oxidation state or more stable oxidation state is +2, such as zinc, tin, cobalt, manganese, iron, calcium, and magnesium. Metals with common oxidation states or stale oxidation states that are not +2 are not divalent metals, such as tungsten and molybdenum.
- the divalent metal comprises zinc.
- the ratio of tin to zinc may range from about 10 to 1 ; to about 1 to 10. In one embodiment the ratio of tin to zinc is about 4 to 1; about 3 to 1 ; about 2 to 1 ; about 1 to 1 ; about 1 to 2; about 1 to 3; or about 1 to 4.
- divalent metals include alkali earth metals, or transition metals.
- tin oxide may be partially replaced with zinc sulfide or zinc
- This substitution may lower the synthesis temperature by at least 100°C from around 1000°C to about 850°C. This also frees the pigment from the requirement that it be cleaned of unreacted stannous oxide or metallic tin by acid extraction.
- the pigment may be substituted by metals other than zinc at the divalent "A" site in this A 2 B 2 0 7 pyrochlore, or AB 2 0 6 foordite structure. This may be accomplished with or without zinc sulfide to lower the onset of reaction.
- Pigments with higher ratios of selenium compared to sulfur tend to have colors that are shifted from a more yellow to a more orange tone.
- X is 0, so the empirical formula for the pigment is M 2 Nb 2 Z 7 .
- M comprises tin and zinc, and Z comprises sulfur and oxygen so that the ZnS:SnO ratio is between 0.04: 1.96 and 0.20: 1.80.
- the pigment has the empirical formula: MNb 2 Z 6 , where M comprises tin and a divalent metal; and Z comprises oxygen and either sulfur, selenium, or a mixture of sulfur and selenium.
- the pigment has the empirical formula: MNb 2 Z 6 , where M comprises tin and zinc; and Z comprises oxygen and either sulfur, selenium, or a mixture of sulfur and selenium
- the inorganic pigments may be synthesized by creating a mixture of metal oxides and intensively blending them in a mixer. The mixture is heated under an inert gas from about 850°C to about 1000°C.
- the color of the pigment may be measured as an acrylic masstone using the
- the color of the acrylic masstone of the pigment has an L* of about 73.7 to about 82.8, an a* of about 4.9 to about 21.1 , and a b* of about 72 to about 84.7.
- the acrylic masstone of the pigment has an L* of about 77.1 to about 78.4, an a* of about 8.0 to about 16.5, and a b* of about 76.6 to about 79.5.
- the acrylic masstone of the pigment has an L* of about 77.1 to about 78, an a* of about 8.0 to about 16.5, and a b* of about 76.6 to about 78.8.
- the crystal structure of the inorganic pigment has an effect upon the color produced by the pigment.
- the inorganic pigment is characterized by an X-ray powder diffraction pattern comprising d-spacings of about 3.095 A, 3.056 A, 2.841 A, 2.645 A, 1.871 A, 1.677 A, and 1.596A.
- the inorganic pigment is characterized by an X-ray powder diffraction pattern comprising d-spacings of about 3.584 A, 3.066 A, 2.836 A, 2.779 A, 2.434 A, and 1.910 A.
- the inorganic pigment is characterized by an X-ray powder diffraction pattern comprising d-spacings of about 3.056 A, 2.647 A, 1.872 A, and 1.596 A.
- the process of making the pigments does not require an acid wash to remove contaminants of stannous oxide decomposition.
- the inorganic pigments may be used in many applications such as coatings, or
- the reflectance properties of the inorganic pigments may be higher at IR wavelengths (greater than 700nm) compared to visible wavelengths (400-700 nm). Infrared reflectance may be measured on the compressed dry powder inorganic pigment using an integrating sphere instrument in accordance with ASTM E903-96. In one embodiment the IR reflectance is greater than about 50%, 60%, 70%, or 80%) on average throughout the region from 700 nm to 2500 nm.
- Example 1 carbonate is made in molar ratios of 0.465, 0.25, 0.015, 0.02.
- the raw batch is calcined as in Example 1 to yield a yellow powder more green in tone than Example 8.
- Example 2 90.85 -0.74 45.32 45.33 90.94 850°C 0.33
- the products of this example exhibit a single pyrochlore phase in their x-ray powder diffraction pattern for ratios of ZnS:SnO between 0.04: 1.96 and 0.20: 1.80.
- the sub-set of such products exhibit uniform shifts in observed color coordinates commensurate with increasing ZnS doping into the pyrochlore lattice showing increased red hue and improvements in yellow masstone.
- At molar ratios of ZnS:SnO of 0.25: 1.75 and above the red hue no longer improves, while yellow tone continues to develop strength.
- This sub-set of products exhibits traces of foordite along with pyrochlore (as the dominant phase) in their x-ray powder diffraction patterns.
