摘要:
This disclosure is directed to porous ceramic processing; and in particular to a method using selected pore forming materials to avoid high exotherms during the ceramic firing process, and the green bodies formed using the selected pore forming materials. The selected pore forming materials are homogeneous wax/non-ionic surfactant particles formed by a prilling process in which the wax is melted and the non-ionic surfactant is mixed into the wax prior to prilling. The disclosure is useful in the manufacture porous ceramic honeycomb bodies including ceramic honeycomb filter traps.
摘要:
Disclosed are novel light polarizing articles comprising a substrate (101), a light polarizing layer (11), an inorganic intermediate layer (107) between the polarizing layer and the substrate, an optional inorganic sub-layer (105) between the substrate and the inorganic intermediate layer, and a protective layer (113) over the light polarizing layer, and method of making the same. Due to the presence of the inorganic intermediate layer and the optional sub-layer, adhesion of the polarizing layer is improved substantially. The light polarizing article has improved chemical, mechanical and thermal resistance. The light polarizing article can be used, for example, as ophthalmic products and in display devices.
