calculate shrinkage

calculation=`[l_1-l_2]/l_1×100`
L1 = separation of sample test markers in initial state
L2 = separation of test marks on final state sample

enter a value:

initial value (l1):
final value (l2):

calculation result:

shrink:
%

calculate moisture content

moisture content=`[w_1-w_2]/w_1×100`
W1 = wet weight
W2 = weight of sample after drying at 110°c

enter a value:

wet weight (w1):
weight after drying (w2):

calculation result:

moisture content:
%

calculate loss on ignition

loss=`[w_2-w_3]/w_1×100`
W1 = wet weight
W2 = dry weight
W3 = weight of sample after heating to approximately 1000°c

enter a value:

wet weight (w1):
dry weight (w2):
weight after heating (w3):

calculation result:

loss on ignition:
%
ceramic heating element ceramic heating element is a device that converts electrical energy into thermal energy. the principle is based on the interaction of thermal and electrical effects.
first of all, the ceramic heating element is composed of ceramic material and resistance wire. when current passes through the resistance wire, the resistance wire will generate heat, which is based on the principle of electrical effect. according to the principle of thermal effect, heat is transferred into the ceramic material, causing it to heat up.
secondly, ceramic materials have high resistivity and low thermal conductivity, which allows the heat generated by the resistance wire to be concentrated in the ceramic material without being lost to the surrounding environment. at the same time, the high temperature stability and chemical stability of ceramic materials also give ceramic heating elements a longer service life.
