A functional patch for a pad is beneficial to a human body and solves the problems entailed in various sanitary pads having a multi-layer configuration such as a sanitary napkin, a diaper for an infant or an adult, a sanitary sheet, a mask, etc. The functional patch is inserted into and attached to the pad formed in a multi-layer. Thus, functionality of a sanitary pad may be improved.

A method for producing a domestic appliance plate from a starting mixture. In order to provide a domestic appliance plate having a high resistance to thermal shock, good thermal insulation, and advantageous mechanical properties, at least magnesium silicate hydrate, kaolinite, calcined kaolinite, and aluminum oxide are used for the starting mixture.

Process for the moderately refractory assembly of at least two articles made of silicon carbide-based materials by non-reactive brazing in an oxidizing atmosphere, in which the articles are placed in contact with a non-reactive brazing composition and the assembly formed by the articles and the brazing composition is heated in an oxidizing atmosphere at a brazing temperature sufficient to melt the brazing composition so as to form a moderately refractory joint, wherein the non-reactive brazing composition is a composition A composed of silica (SiO.sub.2), alumina (Al.sub.2O.sub.3) and calcium oxide (CaO), or alternatively a composition B composed of alumina (Al.sub.2O.sub.3), calcium oxide (Cao) and magnesium oxide (MgO). Brazing suspension, paste comprising a powder of said brazing composition and an organic binder. Refractory joint and assembly.

A refractory article can include a body including a content of alumina of at least 60 wt %, a content of silica of not greater than 20 wt %, a content of zirconia of not greater than 20 wt % for a total weight of the body. In a particular embodiment, the body includes a third phase including composite grains including mullite and zirconia. The third phase including the composite grains can be present within a range including at least 1 wt % and not greater than 35 wt % for a total weight of the body.

The invention concerns a batch for the production of a refractory product, a process for the production of a refractory product, a refractory product as well as the use of a refractory product.

The present disclosure relates to a composite of sintered mullite reinforced corundum granules and a method for its preparation. The composite comprises mullite and corundum in an interlocking microstructure. The process for preparing the composite involves the steps of admixing the raw materials followed by sintering to obtain the composite comprising sintered mullite reinforced corundum granules.

A method of making a refractory article having excellent high-temperature thermal shock resistance and creep resistance is provided. The method includes the step of providing a refractory composition primarily composed of chamotte having controlled particle sizes. The refractory composition may also include mullite, fused silica, calcined alumina and microsilica having controlled particle sizes, and further includes an aqueous colloidal silica binder. The refractory composition is then formed into a refractory article, which is dried and hardened.

A refractory kiln car formed using a refractory composition has excellent resistance to high-temperature thermal shock and creep. The refractory composition is based primarily on chamotte having controlled particle sizes, and may also include mullite, fused silica, calcined alumina and microsilica, having controlled particle sizes. The refractory composition includes an aqueous colloidal silica binder that provides excellent castability and binding between the ingredients following drying.

Disclosed is a ceramic matrix composite (CMC) material including rare earth phosphate ceramic fibers embedded in a ceramic matrix, wherein the ceramic matrix also optionally includes a rare earth phosphate material. Methods for manufacturing the CMC material and gas turbine engine components formed of the CMC material are also disclosed.
