Rubidium (Rb) is regarded as an important “critical metal” mineral resource. Although potential Rb resources are abundant in China, they are characterized with low Rb grades, and are mostly associated with other rare metal deposits. Thus, they are difficult to be exploited. Based on the revie...
Aside from being excellent dielectric materials, mica (a naturally occurring mineral) has almost nothing in common with PTFE (a synthetic fluoropolymer), but because there’s at least one capacitor product series on the market that uses PTFE instead of mica for some capacitance values, both materi...
Types of Vermiculite: There are mainly two types of Vermiculite that are used for different purposes. Crude Vermiculite Exfoliated Vermiculite 1. Crude Vermiculite: Crude vermiculite is vermiculite that has not been heated or expanded. It is the raw form of the mineral before it is processed int...
Hard-paste or also known as true porcelain: Has added mineral materials to the clay, normally mica. It is fired at high temp and results in tougher objects. Soft-paste: This is the least or low type of porcelain. This was discovered by European who fired at lower temps. It is regarded...
The second type of analcime was found as an accessory mineral accompanied by montmorillonite, feldspar, and heulandite/clinoptilolite, and more rarely by erionite, kaolinite, and mica. The pyroclastic rocks are chemically classified into two subgroups, dacitic and andesitic rocks, with an ...
