摘要： Subjects for the invention are to obtain a quartz powder having a high purity and high quality and a process for producing the same and to obtain a glass molding formed by melting and molding the powder and extremely reduced in bubble inclusion. The invention provides a quartz powder, preferably a synthetic quartz powder obtained by the sol-gel method, which, upon heating from room temperature to 1,700° C., generates gases in which the amount of CO is 300 nl/g or smaller and the amount of CO2 is 30 nl/g or smaller.

摘要： A solid oxide cell is provided which, after short-time activation, can generate electricity at a high power density over a prolonged period. This cell can be constituted so as to eliminate the necessity of carrier gas introduction during power generation and, hence, can more easily realize a size reduction in power generation systems. The solid oxide cell at least has an anode having an anode material, a cathode having a cathode material, and an electrolyte disposed between the anode and the cathode and including an ionically conductive solid oxide, wherein the anode material includes a composite metal oxide or a cermet, solid carbon is deposited on the anode material during activation and at least the following reaction schemes (1) and (2) are utilized at the anode during power generation to generate electricity. CO2+C→2CO (1) CO+O2−→CO2+2e− (2)
