The basic structural unit of feldspar is a tetrahedron, which consists of four oxygen atoms surrounding a silicon atom or an aluminum atom. Each such tetrahedron shares an oxygen atom with another tetrahedron to form a three-dimensional skeleton. Large radius alkali or alkaline earth metal cations are located in large voids within the framework with coordination numbers of 8 (in monoclinic feldspar) or 9 (in triclinic feldspar).

A platinum powder of micron size with a spherical shape and a polygonal shape. The solid density is 1.0 to 4.0 g/cm3. The average particle size is 1.1 to 1.7 μm. The specific surface area is 5 to 15 m 2 /g. Dissolve sponge platinum with aqua regia to obtain chloroplatinic acid solution, adjust acidity, add dispersant, heat stir, add reducing agent (hydrazine hydrate, etc.), let stand cooling, wash and dry to obtain average particle size 0.5μm Fine platinum powder. 

Supply stannic oxide (SnO2) for sell

Submitted by admin on Mon, 12/17/2018 - 08:39

Stannic oxide SnO2 is also an excellent transparent conductive material. It is the first transparent conductive material to be put into commercial use. In order to improve its conductivity and stability, it is often used for doping, such as SnO2:Sb, SnO2:F, etc. Both SnO2 and its doping have a tetragonal rutile structure. Red is O, black is Sn, and SnO2 is composed of two Sn and four O atoms. The lattice constant is a=b=0.4737nm, c=0.3186nm. , c / a = 0.637. O2-=0.140 nm, Sn4+=0.071 nm.

Lead stearate dibasic manufacturer

Submitted by admin on Fri, 12/14/2018 - 07:36

Lead stearate dibasic is a white powder, insoluble in water, soluble in hot ethanol, benzene and turpentine. It is heated and dissolved in an organic solvent and cooled to form a gel. It is decomposed into stearic acid and the corresponding salt in the presence of strong acid, and is hygroscopic. This product is toxic and susceptible to sulfide contamination. Do not dissolve in water, soluble in hot ethanol. Melting point 103-110 ° C
