    Abstract: To provide powder for thermal spraying, a method of thermal spraying, and a thermally sprayed coating, which can efficiently work supplying of a dry state powder by using a powder supplying apparatus with a thermal spraying apparatus, and which prevent variation and pulsation or lowering of supplied amount of powder and achieve a required film forming rate, and can obtain a denser coating on the surface of the substrate to be thermally sprayed. [Solution] Powder for thermal spraying 1 is a powder mixture obtained by mixing ceramic powder A whose particle diameter is D 1 and ceramic powder B whose particle diameter is D 2 , wherein D 1 is 0.5 to 12 μπι as a median diameter, D 2 is 0.003 to 0.100 μιη as an average particle diameter converted from the BET specific surface area, and when, in the powder mixture, the total weight of the ceramic powder A to be used whose prescribed particle diameter D 1 is W 1 , and the total weight of the ceramic powder B to be added to the ceramic powder A is W2, an addition ratio Y of the ceramic powder B defined by Y = W 2 / (W 1 + W 2 ) satisfies: Y ≥ 0.2066 x D 1 -0.751 and Y ≤ 0.505 x D 1 -0.163 .

    Abstract: A highly purified diatomite composition may indude greater than or equal to 90% silica, from about 0.5% to about 5% of a calcium-containing compound, and less than or equal to about 2% total of aluminum-containing oxides and iron-containing oxides. A method of making a highly purified diatomite composition may include providing a diatomite comprising at least 5% of a calcium-containing compound, calcining the diatomite, and acid washing the calcined diatomite. The calcined, acid-washed diatomite may include less than or equal to about 1 % total of extractable aluminum-containing oxides and iron-containing oxides, and less than or equal to about 5% of the calcium-containing compound. The acid washing may include an acid selected from the group consisting of sulfuric acid (Η 2 SO 4 ), hydrochloric acid (HCI), and nitric acid (HNO 3 ). The method may not include a flotation step.
