Tourmaline crystals are the world best material existing for avionics sensors, they keep better their properties to higher temperature than any other natural or man-made material.
The reason it's not widely used?
The difficulty of sourcing due to it's natural origin : it comes from thousands of small producing mines wordwide and they have to be sorted carefully by it's chemical composition.
The experience we have with a 20 years contract of exclusive supplying to a global sensor manufacturer, mining this rare material in our claims in Brazil , together with an unique and exceptional stock, turn us able to guarantee you the best piezoelectric tourmaline, allowing you to develop the world best sensors.
As mine owner of "Copacabana" granite, and others. We propose granite blocks for sale at very interesting prices. We could consider a partnership whit a distributor who whilst investing in the block production could beneficiate of even more reduced prices for its blocks. We may even consider an exclusivity partnership.
