thermosetting resins bismaleimide meosoporous silica dielectric properties structure-property
2011/1/4
New composites with improved thermal stability, mechanical and dielectric properties were developed, which consist of 2,2!-diallylbisphenol A (DBA)/4,4!-bismaleimidodiphenylmethane (BDM) resin and a n...
Synthesis and thermal stability of hydrotalcites based upon gallium
Hydrotalcite Hydrocalumite Gallium Synthesis Thermal stability
2009/9/30
Hydrotalcites based upon gallium as a replacement for aluminium in hydrotalcite over a Mg/Al ratio of 2:1 to 4:1 were synthesised. The d(003) spacing varied from 7.83 ?for the 2:1 hydrotalcite to 8.15...

Charmarite Rhodochrosite Hydrotalcite Hydrocalumite Synthesis Thermal stability
2009/8/28
The hydrotalcite based upon manganese known as charmarite Mn4Al2(OH)12CO3·3H2O has been synthesised with different Mn/Al ratios from 4:1 to 2:1. Impurities of manganese oxide, rhodochrosite and bayeri...
Enhanced Thermal Stability of Al-Pillared Smectites Modified with Ce and La
Bentonite Ce La Pillared Clays
2000/8/1
Abstract: A commercial bentonite (primarily smectite) from Fischer Scientific Company (F bentonite) and a natural bentonite from Peru (P bentonite) were used in the preparation of pillared clays with ...
High form of pentlandite and its thermal stability
High form pentlandite thermal stability
1998/1/30
The high-temperature form of pentlandite (Fe4.5Ni4.5S8) was found to be stable between 584 6 3 and 8656 3 8 C, breaking down into monosulfide solid solution and liquid at the later temperature. The ph...
