The crystal tourmaline (Tourmaline)
¡¡¡¡crystal tourmaline chemical composition is complex, is take contains the boron as the characteristic aluminum, the sodium, hard, the magnesium, the lithium ring structure silicate mineral. Produces generally in the flowered hillock pegmatite and the high temperature was mad in the hydrothermal ore deposit, is one of one kind of typical high temperature pneumatogenic minerals. ª¥
¡¡¡¡ The crystal tourmaline crystallizes the condition good tourmaline, has the rule shape, has the higher use value.
¡¡¡¡ The natural black tourmaline carries on the heat treatment after the reducing atmosphere condition, may have high compared to the far infrared ceramics powder infrared compared to the emissivity value, its infrared radiation peak value and the wien law have the very good corresponding relations, under the room temperature the peak value radiation wave length is about 9.5um. yang slow admonishes «µ the red øÊ ¯µ that high flame partner øÉ to rinse the small box to pound the crag ýÆ quail child moat grave afraid perspiration to mow¢¡The H felt deep-rooted ulcer tooth ûÓ manganese yang slow admonishes red «µ øÊ ¯¿ ª·¢³ping the curtain robs the zinc duckweed illness úÆ to punish

This textile fiber may strengthen the human body physiology function effectively through the promotion blood circulation, the concrete process is includes the tourmaline pellet (disperses evenly in among) the man-made silky fiber solution, the spinning and weaving becomes the textile fiber shape, but makes results in the electret textile fiber.
¡¡¡¡ Because the tourmaline mineral crystal has the piezoelectricity performance, this characteristic is widely applied in the radio industry, available electrical stonemason's workshop wave length adjuster, in polariscope polaroid. Crystal complete, not curving, non-crack tourmaline, may make the piezometer which in the determination air and the water the ramming uses, but also available in sound navigation and ranging part, on determination material standard letter, instrument and industrial equipment part and so on, if uses in the skin epidermis the electricity generation controller, designs the permission light through the drugs nearby region, guides the undulation field in the photoemission direction. Moreover also uses in including the parabolic cylinder reflection direction guidance undulation field. Moreover also uses in including the parabolic cylinder reflector and including the electric current output tourmaline crystal electrokinetic transducer. Many science and the industry instrumentation tourmaline, is the electrical pliers, can demonstrate the light the polarization. Because the tourmaline not only is the pyroelectricity also is piezoelectricity, namely when heating or compression all can produce the electricity, the medicine of a hot nature gauge is surveys the radiation to be mad the intensity the early instrument, it also is relies on the tourmaline thermoelectricity characteristic.
