Alkali feldspars constitute a solid-solution between K-feldspar or orthoclase molecule (Or) and albite (Ab), which represents also the sodic end-member of the plagioclase series. Anorthite (Ca[Al 2 Si 2 O 8]; An) is present in small quantities in alkali feldspars, usually constituting less than 5% of the solid solution and predominantly found in Na-rich alkali …

Americans consume far too much sodium — about 3,500 milligrams daily. The American Heart Association recommends no more than 2,300 mg a day and moving toward an ideal limit of no more than …
Feldspar - Mineralogy, Crystallography, Structure: Sanidine and orthoclase are monoclinic or nearly so; the plagioclase feldspars are triclinic. All, however, have the same fundamental structure: it consists of a continuous, negatively charged, three-dimensional framework that is made up of corner-sharing SiO4 and AlO4 tetrahedrons …

The plagioclase feldspars are triclinic. The plagioclase series follows (with percent anorthite in parentheses): Albite (0 to 10) NaAlSi3O8, Oligoclase (10 to 30) (Na,Ca)(Al,Si)AlSi2O8, Andesine (30 to 50) NaAlSi3O8—CaAl2Si2O8, Labradorite (50 to 70) (Ca,Na)Al(Al,Si)Si2O8, Bytownite (70 to 90) (NaSi,CaAl)AlSi2O8, Anorthite (90 to …
Feldspars are aluminosilicates containing varying amounts of calcium, potassium, or sodium. In glassmaking, feldspar provides alumina for improving hardness, durability, and resistance to chemical corrosion. In ceramics, feldspar is used as a flux, lowering the vitrifying temperature of a ceramic body during firing and forming a glassy phase.

This mineral is often called potassium feldspar or K-feldspar because potassium always exceeds sodium in its formula. Potassium feldspar comes in three different crystal structures that depend on the temperature it formed at. Microcline is the stable form below about 400 C. Orthoclase and sanidine are stable above 500 C and …
The Sodium Correction Rate for Hyponatremia Calculates recommended fluid type, rate and volume to correct hyponatremia slowly (or more rapidly if seizing).

Feldspar, any of a group of aluminosilicate minerals that contain calcium, sodium, or potassium. Feldspars make up more than half of Earth's crust, and professional literature about them constitutes a large percentage of the literature of mineralogy. Learn more about the properties and uses of feldspar in this article.
Feldspar are a class of rock-forming tectosilicate minerals that contains calcium, potassium or sodium and makes up more than half of the earth's core by weight. Its minerals are largely found in igneous, sedimentary and metamorphic rocks spread across different parts of the world. These minerals are such essential components of these rocks ...
Because sodium is extremely reactive, it never occurs in the free state in Earth's crust. In 1807 Sir Humphry Davy became the first to prepare sodium in its elemental form, applying electrolysis to fused sodium hydroxide (NaOH). Sodium is an important constituent of a number of silicate materials, such as feldspars and …
According to the Dietary Guidelines for Americans, Americans should consume less than 2,300 milligrams of sodium per day as part of a healthy diet regimen, but the majority of adults eat more than 3,400 mg of sodium each day. Consuming too much sodium can bring about some serious health concerns, such as high blood …
Dissolution of sodium and potassium feldspar in HF/HCI acid mixtures 1327 for H'/HF = O-03: A1F4.5, SiFs., for H'/HF = 100: AIF,.+ SiF1.6. Although acids other than hydrofluoric cannot dissolve a silicate to any appreciable extent, they may react with aluminosilicates by partial dissolution, thereby changing ...
Feldspar - Mineral Composition, Uses, Types: All the rock-forming feldspars are aluminosilicate minerals with the general formula AT4O8 in which A = potassium, sodium, or calcium (Ca); and T = silicon (Si) and aluminum (Al), with a Si:Al ratio ranging from 3:1 to 1:1. Microcline and orthoclase are potassium feldspars (KAlSi3O8), usually …
Feldspar - Ceramics, Glass, Fertilizer: Feldspars are used widely in the glass and ceramics industries. Alkali feldspars are more commonly used commercially than plagioclase feldspars. Albite, or soda spar as it is known commercially, is used in ceramics. The feldspar-rich rocks larvikite and a few anorthosites are employed as both interior …
The dynamic evolutions of fluid-mineral systems driving large-scale geochemical transformations in the Earth's crust remain poorly understood. We observed experimentally that successive sodic ...

Check the fine print on the packaging for terms like "broth," "saline" or "sodium solution." Sodium levels in unseasoned fresh meats are around 100 milligrams or less per 4-ounce serving. Compare this with the same serving of prepared rotisserie chicken pre-seasoned with sodium, which can have 400 mg of sodium a serving!

Low blood sodium is common in older adults, especially those who are hospitalized or have long-term health problems such as heart disease, kidney disease or cancer, among others. Symptoms of hyponatremia can include nausea and vomiting, loss of energy and confusion. Serious hyponatremia can cause seizures, coma and even death.
Teresa A. Hillier, MD, MS, was a practicing endocrinologist and senior investigator at the Kaiser Permanente Center for Health Research.

Feldspars of importance to ceramics are aluminosilicates of sodium, potassium, and calcium (Jones & Berard, 1993) They are used as fluxes to form a glassy phase in bodies, thus promoting vitrification and translucency.They also serve as a source of alkalis and alumina in glazes. The pure spars are albite (NaAlSi 3 O 8), orthoclase or microcline …
