76 results about "Feldspar" patented technology

Feldspars (KAlSi₃O₈ – NaAlSi₃O₈ – CaAl₂Si₂O₈) are a group of rock-forming tectosilicate minerals that make up about 41% of the Earth's continental crust by weight. Feldspars crystallize from magma as veins in both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar is known as anorthosite. Feldspars are also found in many types of sedimentary rocks.

In the drilling verification link, a local natural mineral base material is compounded with an environment-friendly mud, layered adaptive drilling is adopted, drill cuttings-mud in-situ aerobic composting is carried out, and the composting products are backfilled and repaired in cooperation with local dominant plant seeds, so that rapid ecological restoration is realized.

Preparation method of super-smooth white glaze for daily use porcelain

The application discloses a preparation method of super-smooth daily-use porcelain white glaze, which completely replaces traditional quartz as a main silicon source with an industrial by-product lithium residue, introduces bismuth oxide (Bi2O3) as an efficient fluxing agent, and supplements tin oxide (SnO2) and antimony oxide (Sb2O3) as functional additives to form a K-Na-Ca-Mg-Sb-Bi multi-element eutectic system; and introduces potassium nitrate (KNO3) as an oxidation stabilizer to inhibit the precipitation of bismuth-based microcrystals and eliminate the yellowing phenomenon of the glaze surface caused by the change of the valence of bismuth elements, so that high-quality glaze surfaces with super-smooth surfaces and high whiteness are successfully obtained while the firing temperature is significantly reduced. The application significantly reduces the dependence on traditional non-renewable mineral resources such as high-grade quartz and feldspar, saves the raw material cost, meets the needs of green environmental protection and circular economy development, and provides a new path for the sustainable development of the ceramic industry.
