The present invention relates to zirconium silicate compositions having a lead content that is below 0.6 ppm and methods of manufacturing zirconium silicate at reactor volumes exceeding 200-L with a lead content below 1.1 ppm. The lead content of the zirconium silicate of this invention are within the levels that are considered acceptable for extended use given the dose requirements for zirconium silicate.

The present disclosure relates to nanomaterial composites capable of selectively extracting lithium from a lithium-containing liquid resource when the nanomaterial composite is activated, a method of preparing the nanomaterial composites, and the use of the nanomaterial composites for the extraction and recovery of lithium.

An ammonia adsorption product is described which may be used for fresh caught fish and bait. The product may comprise functionalized tectosilicate compound and a buffer. High concentrations of ammonia produced by fish waste can be lethal, even though oxygen availability is rich enough to keep fish breathing. The product is a user-friendly, sustainable, affordable product which is able to extend the life of the fish by safely removing ammonia by an ion-exchange mechanism. This product can convert toxic ammonia into ammonium and uptake ammonium by releasing sodium ions in the water.

A method includes contacting a metallic compound comprising a first metallic cation, with a melt comprising a metallic polysulfide comprising a second metallic cation, thereby forming a molten metallic polysulfide of the first metallic cation. The method also includes cooling the melt to form a sulfur phase and a solid phase comprising the molten metallic polysulfide of the first metallic cation.

A zeolite membrane structure includes a porous support, and a zeolite membrane. The zeolite membrane has a first zeolite layer located in a surface of the porous support, and a second zeolite layer located outside of the surface of the porous support and integrally formed with the first zeolite layer. The porous support has an outermost layer in which the first zeolite layer is located. An average thickness of the first zeolite layer is less than or equal to 5.4 micrometers. A porosity of the outermost layer is greater than or equal to 20% and less than or equal to 60%.

The present invention relates to novel microporous zirconium silicate compositions that are formulated to remove toxins, e.g. potassium ions, from the gastrointestinal tract at an elevated rate without causing undesirable side effects. The preferred formulations are designed avoid increase in pH of urine in patients and/or avoid potential entry of particles into the bloodstream of the patient. Also disclosed is a method for preparing high purity crystals of ZS-9 exhibiting an enhanced level of potassium exchange capacity. These compositions are particularly useful in the therapeutic treatment of hyperkalemia.
