This research has characterized the effects of P 2 O 5 additions on the physical, chemical,
thermal, rheological properties and the structure of SiO 2-B 2 O 3-Na 2 O glasses relevant to …

Spinel crystals precipitate in high-level waste glasses containing Fe, Cr, Ni, Mn, Zn, and Ru.
The liquidus temperature (TL) of spinel as the primary crystallization phase is a function of …

Three aspects of the kinetics of spinel crystallization in a high-level waste (HLW) glass were
studied:(1) the effect of nucleation agents on the number density (ns) of spinel crystals,(2) …

The liquidus temperature of spinel (AB 2 O 4) crystals frequently limits the waste loading of
vitrified nuclear waste. In other studies, glass structure-spinel liquidus temperature …

The equilibrium concentration (C o) of spinel was measured in 16 high-level waste (HLW)
glasses as a function of temperature (T). Glasses were formulated by increasing or …

Liquidus temperature (TL) was measured for 38 simulated high-level waste borosilicate
glasses covering a Hanford composition region, using optical microscopy and crystal …

It has been a commonly held assumption that constraining liquidus temperature (TL)
prevents the accumulation of crystalline phases in the high-level waste (HLW) glass melter …

The liquidus temperature (TL) and the equilibrium mass fraction of spinel were measured in
the regions of low-silica (less than 42 mass% SiO2) high-level waste borosilicate glasses …

Spinel concentration in MS-7 glass (0% others) with its limited components shows to be
dependent on several variable properties during heat treatments, primarily the limited …

A large fraction of HLW glass readily precipitates spinel. The presence of solid particles,
including spinel crystals, is undesirable in a high-level waste (HLW) glass melter because …
