We developed new-type granulated raw powder formed from soda-lime-glass batch components by using a spray-drying machine. We dropped new-type granulated raw powder directly into an oxygen–excess gas burner with a vertical downward converging flame. Partially or fully melted materials with powder-like shapes were formed in the flame by “in-flight melting materials mehod”. We developed and produced special in-flight glass, glass powder with specific elemental components, within one second by the in-flight-melting method with the methane (13A) and oxygen gas burner (~30cm). We also produced the needle-like fibers with from a few tens of nanometer to sub-micron in diameter and with more than a few tens of micrometer length.
