A multilayer tube includes: an inner layer including a polymer, wherein the polymer includes a fluoropolymer, a polyolefin, a blend thereof, or combination thereof; and an outer layer adjacent to the inner layer, wherein the outer layer includes a polymer including a fluoropolymer, a polyolefin, a blend thereof, or combination thereof; wherein the inner layer, the outer layer, or combination thereof includes at least one blocking agent, wherein the at least one blocking agent reduces the percent transmission by at least 99% at wavelengths between 240 nm to 450 nm.

A phosphor in glass (PiG) cover is provided to modulate the color emitted from an LED chip. The PiG cover includes an active layer including glass and phosphor, and a secondary layer including glass and free of phosphor. The active layer is stacked on the secondary layer to form the PiG cover. Alternately the PiG includes an active layer sandwiched between two secondary layers. Two or more active layers can be stacked to each other or disposed side-by-side. An LED chip is arranged under the PiG cover to form an LED package.

A sintered machinable glass-ceramic is provided. The machinable glass-ceramic is formed by mixing phyllosilicate material having a sheet structure, with a glass fit and firing the mixture at relatively low temperatures to sinter the phyllosilicate, while maintaining the sheet-like morphology of the phyllosilicate and its associated cleaving properties. The sintered machinable glass-ceramic can be machined with conventional metal working tools and includes the electrical properties of the phyllosilicate. Producing the sintered machinable glass-ceramic does not require the relatively high-temperature bulk nucleation and crystallization needed to form sheet phyllosilicate phases in situ.

Modified copper chromite spinel pigments exhibit lower coefficients of thermal expansion than unmodified structures. Three methods exist to modify the pigments: (1) the incorporation of secondary modifiers into the pigment core composition, (2) control of the pigment firing profile, including both the temperature and the soak time, and (3) control of the pigment core composition.

A low K value, high Q value, low firing dielectric material and method of forming a fired dielectric material. The dielectric material can be fired below 950&#xb0; C. or below 1100&#xb0; C., has a K value of less than about 8 at 10-30 GHz and a Q value of greater than 500 or greater than 1000 at 10-30 GHz. The dielectric material includes, before firing a solids portion including 10-95 wt % or 10-99 wt % silica powder and 5-90 wt % or 1-90 wt % glass component. The glass component includes 50-90 mole % SiO, 5-35 mole % or 0.1-35 mole % BO, 0.1-10 mole % or 0.1-25 mole % AlO, 0.1-10 mole % KO, 0.1-10 mole % NaO, 0.1-20 mole % LiO, 0.1-30 mole % F. The total amount of LiO+NaO+KO is 0.1-30 mole % of the glass component. The silica powder can be amorphous or crystalline.
