1 Synthetic Corundum is one of our strong products.

2 Corundum refractory material is an excellent lining material for carbon black reactors and can be used for a long time in the reducing atmosphere.

3 The utility model relates to a corundum sieve tube used in the field of oil field and oil well production.

4 In this paper, the penetration of the nubbly corundum concrete by projectiles with different hit velocity is experimentally studied.

5 The new - type of ultrafine corundum abrasive materials, prepared by sol - gel technique, have excellent grinding performance.

6 Hardness than corundum, abrasive easily broken, sharp edges and corners, good cutting, grinding heat and small.

7 Being three dimensional net shaped microporous structure, the corundum filter plate comes to good filteration result and improves the melt spinnability and the fibers quality.

8 Corundum brick and chrome - corundum brick are the key refractories for gasifier and furnace in petrochemical industry.

9 Corundum, acryl and natural materials such as wood, stone, rubber, leather can all be cut by using CO.

10 It is closely related to the corundum structure except the cations are of two different types.

11 Corundum—Mullite Board: It is made by high sintering corundum and mullite together.

12 Brown corundum, white corundum or carborundum polishing grinders should be used according to the processes materials.

13 The properties of corundum - mullite - zirconia grogs made by reaction - sintering process and their carbon - bonded materials have been investigated.

14 It introduces process control point of chrome corundum permeable brick and its application in smelting ferroalloys.

15 Barmac grains and ball milling grains are brown corundum grains from different granulating process.

16 Production technology of rebonded corundum brick made from sintered alumina and tabular alumina has been introduced.

17 Used for corundum bricks, mullite bricks, silicate bricks masonry in blast furnaces, hot air stoves.

18 Chromium oxide green with corundum crystal structure has such characteristics as high thermal stability, high painted capacity, chemical corrosion-resisting capacity, etc.

19 Moreover, the higher the hit velocity, the higher anti-penetration capability of the nubbly corundum concrete than that of common concrete or rock.

20 The influence of nano - silica on the properties and microstructure of corundum castable is studied.

21 This is because nano - silica can accelerate the sintering process and promote the densification of corundum castable.

22 The exoplanet's atmosphere condenses out minerals such as enstatite, corundum, spinel, and wollastonite.

23 It is considered that the deposit is an anatectic migmatite corundum deposit.

24 This paper emphasizes the development, quality and application of corundum castable refractories of high purity, low cement-content.

25 Sandblasting is the most commonly used coarsening process, in sharp sand, hard as well, the use of quartz sand, corundum and so on.

26 Any of various yellow gemstones, especially a yellow variety of sapphire or corundum.

27 Results indicate that V 2 O 5 - doped corundum ceramics can lower sintering temperature under not lowering mechanical properties conditions.

28 Aluminum-silicon composite ultra-fine fume is a fume mineral additive with utility model patent,[www.Sentencedict.com] which won Fume Mineral Admixtures Extracted from Corundum Soot and Production of Synthetic Potash.

29 Other industrial products are mainly coal, zirconia, powder metallurgy, corundum and so on.

30 The series of tackifiers are manufactured high-grade high-alumina powder, corundum powder, micropowder inorganic bonder and additional agent.
