NOVEL GLASS ELEMENTS FOR USE IN BALANCES

摘要

we have developed a glass elements (14, 16, 18, 20) improved with temperature coefficients of modulus of elasticity is very low, used as a measure of balance in order to determine the mass of objects with a high degree of resolution.a preferred embodiment of the invention is to achieve from a glass containing sio2 60,98%, 14.7% b2o3, na2o, al2o3, 8.94%, 4.72% and 10.9% bao, by weight.
